The name of the method was a lie. The comment was a lie.

* [mini] double quote linker path in defined(LD_NAME) case

In
https://github.com/dotnet/runtime/commit/e71a9583b4d6c9bd97edd87cda7f98f232f63530
we started setting a default `LD_NAME` for x86 non-mach targets

Fixes Android x86 builds that specify a `tool_prefix` with spaces in it

* also add an "llvm_only" branch to the defined(LD_NAME) case

- new sample for DLLImport on wasm
- license headers
- refactor withModuleConfig to advanced sample
- removed withConsoleForwarding from samples

* [mono] Disable failing Globalization and Transactions tests

The System.Transactions.Tests.OleTxTests aren't supported by Mono on Windows: https://github.com/dotnet/runtime/issues/74187

The System.Globalization test failure is a real issue that is being investigated: https://github.com/dotnet/runtime/issues/74179

* Disable InvariantMode tests as well

In stress scenarios with inconsistent weights, it was possible
to change the condition weight from zero to non-zero without
resetting the "rarely run" bit. Use `inheritWeight()` to set
the weight, which handles this case.

Fixes #74218

This makes it easier to use `superpmi.py collect` to collect
repro cases of JIT asserts or crashes (as a follow up to #69494).
Remove switch `--skip_clean_and_verify_step` and add `--clean` to
specifically request the collection be cleaned (and verified).
The `--clean` switch is added to the CI collection jobs.

* Add faster EnumMemoryRegion with less memory usage

Issue: https://github.com/dotnet/runtime/issues/72148

Instead of drilling down into all the individual MT/MD/EEClass, etc. data structures, add the LoaderAllocator/LoaderHeaps regions directly.

Add new CLRDATA_ENUM_MEM_HEAP2 flag for the fast path.

To reduce risk of incomplete core dumps this is enabled by the COMPlus_EnableFastHeapDumps env var. This env var is only looked at by
the Linux/MacOS createdump. It is currently ignored on Windows. The new HEAP2 flag is works when passed to the EnumMemoryRegions API
on Windows but createdump can't set it because MiniDumpWriteDump in dbghelp.dll loads/calls the DAC API.

Fix MacOS dlopen error message

https://github.com/dotnet/RUNTIME/pull/74433.patch works but https://github.com/dotnet/runtime/pull/74433.patch leads to 404, opened a ticket with GitHub: `#1757301`

* Fix RegexExperiment.ViewSampleRegexInDGML test

This stopped working after some recent changes to NonBacktracking.

* Update src/libraries/System.Text.RegularExpressions/tests/FunctionalTests/RegexExperiment.cs

* Remove unused _readFirstEntry. Remnant from before we created PaxGlobalExtendedAttributesEntry.

* Set the position of the freshly copied data stream to 0, so the first user access of the DataStream property gives them a stream ready to read from the beginning.

* Process a PAX actual entry's data block only after the extended attributes are analyzed, in case the size is found as an extended attribute and needs to be overriden.

* Add tests to verify the entries of the new external tar assets can be read. Verify their DataStream if available.

* Add copyData argument to recent alignment padding tests.

* Throw an exception sooner and with a clearer message when a data section is unexpected for the entry type.

* Allow trailing nulls and spaces in octal fields.

* Throw a clearer exception if the unsupported sparse file entry type is encountered. These entries have additional data that indicates the locations of sparse bytes, which cannot be read with just the size field. So to avoid accidentally offseting the reader, we throw.

* Tests.

* Rename to TrimLeadingNullsAndSpaces

* Rework fgComputeReachability
* Rework optSetBlockWeights
* Rework optVnCopyProp
* Rework things for optRedundantBranches

This has a few small diffs, as I had to disable jump threading in one
case and generalize how morph updates the loop table.

* Rework optOptimizeValnumCSEs
* Rework assertion prop
* Rework range prop
* Rework second flow opt and edge weight phases
* Rework fgDetermineFirstColdBlock
* Rework fgSimpleLowering
* Rework linear scan
* Rework placeLoopAlignInstructions
* Enable checks after fgMorphArrayOps
* Enable remaining phases.
* only dump starting messages under verbose

* Use the regType for extracting the RegisterType

* Add test case

* #50575 color behaviour by default is enabled on android/applemobile 

* Only enable Arm intrinsics for full aot

* Make sure AOT doesn't fall back to interpreter

* Remove assert in System.Net.Http.Http3Connection.SendAsync

* Minor change

We used to exclude locals with the flag set from SSA; this should no longer be necessary.

* Fixed check for Int128 in the routine used to abort marshalling Int128 parameters in R2R

* Fix test to tolerate unaligned Int128 data

* Fix per-call stack checks on x86

This is invoked in debug JIT builds using `COMPlus_JitStackChecks=2`
or in JIT stress. It wasn't forcing the created local variable to be
`lvDoNotEnregister`. Not sure why this wasn't showing up more
commonly; maybe because the asserts were incorrectly noway_assert.

Fixes #74129

* Initialize lvaReturnSpCheck, lvaCallSpCheck

* Skip directory symlink recursion on TarFile archive creation

* Add symlink verification

* Address suggestions by danmoseley
