It is the case that the IR supports the "zero" node for structs
in two positions: on the RHS of an assignment (InitBlk form) and
under a return, in case the ABI return type is scalar.

Meanwhile, assertion propagation "blindly" replaced structs with
zeroes, and so workarounds had to be applied in order for the IR
to remain valid, in the form of the NO_CSE flag, applied either
explicitly (multi-reg returns) or implicitly (ADDR(LCL) created by
"impNormSturctVal" for call args).

This was:

a) A CQ problem in cases where we forgot to clear the NO_CSE flag
   when the node's parent was updated, say after inlining.
b) A burden for enabling struct LCL_VAR arguments, as one had to
   remembered to mark them NO_CSE in all situation.

This change fixes the problem by deleting propagation of zeroes for
local uses, instead propagating them as part of their parents (ASGs
and RETURNs).

This has the CQ benefits of not being affected by stale NO_CSEs and
the drawback of not participating in the "chained" propagation, where
we first copy-propagated something, and then zero-propagated into the
new local as well. These cases seem rather rare, so I decided not to
spend TP on fixing them by looking at the copy assertions in the new
code.

This change also deletes the zero propagation code for SIMDs. It was
only useful in cases we had a promoted SIMD field that was zero-inited
via an InitBlk on the parent struct. That promotion code was (and is)
creating nodes that look like integral constants, except they are of
TYP_SIMD. We should delete that form and use proper SIMD zero nodes
instead, and design the propagation story for them separately.

This allows us to remove a bunch of huge tables that weren't actually needed.
Removes support for setting MONO_EXTERNAL_ENCODINGS env var which is discouraged.
Also removes the code for .mdb debug symbol support which was already disabled everywhere.

Fix OSR jitstress failures by disabling STRESS_LCL_FLD for two cases:
* for Tier0 methods with patchpoints (because patchpoint info generation
does not produce the right offsets when locals are padded)
* for OSR locals in OSR methods (because they live on the Tier0 frame and
so can't have their storage altered.

Enable struct promotion for OSR locals. In most cases this ends up being
dependent promotion. Enabling independent promotion will take more work.

* GetTypeField should return ELEMENT_TYPE_BYREF.

* Remove setting of token2 in all cases. This value is not used in any
scenario and therefore is more confusing than helpful. Add a comment about
the expectations of the returned values.

* Setup pipeline and setup for testing.

* Updated scenario names for new scenario name setup and added no animation tests.

* Revert "Setup pipeline and setup for testing."

This does a few things:
- The previous changes for Antimirov changed the representation from being represented as a DfaMatchingState to instead being a list of states.  Unfortunately, this came at the expense of a significant increase in overhead for the DFA mode.  This commit melds the old and new design, by still using a CurrentState struct that can be either a DFA state or an NFA state, but with a simplified representation that lacks any processing.  The processing is left to two separate structs that implement static abstract interface methods, as was previously done, using that to provide streamlined, generic-specialized processing for the DFA path.
- Overhauled how we switch from DFA mode to NFA mode.  Previously, the builder would store whether we were in NFA mode, and any matching after it had been switched over immediately started in NFA mode.  We now always start in DFA, and only switch over to NFA if we try to create a new state but doing so would exceed the graph size constraint.
- Overhauled how we handle the outer/inner loop logic.  Previously we wanted to remain in a tight inner loop and so would use some "leeway" to allow us to go beyond the graph size constraint in order to avoid having to check too frequently whether we'd exceeded that size.  Now, the transition function itself returns whether we need to exit out to the outer loop in order to upgrade from DFA to NFA, and until/unless that happens, we can stay in the inner loop.
- Avoids inlining huge amounts of NFA code that can result in worse DFA code
- Renamed Brzozowski and Antimirov to DFA and NFA.
- Added a lot of comments to SymbolicRegexMatcher
- Fixes "watchdog" issue with captures
- A few other renames / cleanups.

We currently either guess at some of this state based on the immediate surrounding nodes (e.g. whether the immediate child backtracks) or we do potentially-expensive walks each time we need to check (e.g. walking all ancestors until root to determine whether a given node is to be considered atomic).  This changes the code to do a pass over the graph to compute the relevant information, which can then be used by the code generators any time they need to access that information.  This provides the code with faster and more accurate answers.

As JanV noticed during an independent investigation,
TypeGeneratorTests historically used to produce an enormous amount
of stdout spew due to individually reporting the details of all
passing test cases; for the entire set of 1501 tests the total
size of the spew was about 150 MB. In combination with the change
to capture stdout spew in the xml test reports this effectively
canceled out all previous wins achieved via test merging - in fact,
the tests became twice as slow compared to before the merging.

This modification only reports mismatches i.e. failures where we
don't receive the expected answer in one of the test cases. This
reduces the total spew from 150 MB to just over a megabyte and
restores the perf improvement achieved via test merging.

This change adds initial provisions for platform detection similar
to library logic to CoreCLRTestLibrary and marks a few
architecture-conditional tests with ConditionalFact attributes.

While I must admit I'm not happy about the IL representation of
the ConditionalFact attributes, it's technically using the same
representation as the library tests do and it only affects a handful
of tests. During consolidation of the remaining tests we'll
continue working on an easier solution even though it may require
diverging further away from Xunit.

I'm not yet removing the CLRTestTargetUnsupported clauses from
the corresponding project files, that can only be done after
switching these tests over to use the merged wrappers (my next
change) as the legacy XUnit wrapper generator (in particular the
test execution script generator) relies on those properties.

Thanks

Tomas

* [tests] Pass PDB delta to ApplyUpdate

* extra tracing output

* Return 0 if a method has no sequence points

   -1 means there was some kind of problem

   0 means 0 sequence points

   In particular for mono_ppdb_get_seq_points_enc a compiler-generated method might have 0 sequence points in the PDB delta, but we should consider that as ok, and not fall back to looking in the baseline image

* pass MONO_DEBUG=getn-seq-points to hot reload tests

   For platforms where we use the remote executor, set the environment variable when starting the remote process.

   For WASM, pass --setenv when building the project.
