* 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

* Fix mono package versions during stabilization

The issues that are being fixed via this PR happened and were fixed during the 7.0 stabilization release exercise.

* Cleanup current directory tests

Replace hardcoded list of platforms with symlinked temp directory with a relaxed condition that allows the test to pass even when the temp directory is symlinked.

* Fix OSX test failures

/tmp does not seem to be an ordinary symlink
