AArch64 macOS: OMR fvtest failures

[knn-k]

Many fvtest programs fail on AArch64 macOS as shown below.

omrporttest calls omrmem_allocate_memory32(), which always returns NULL on AArch64 macOS.
But that is not the reason of "Could not find 0x4000 bytes available with page size 0x4000". That is a different problem.

I opened Issue #6739 for omrsysinfo_get_processor_description() on macOS.

[knn-k]

PR #6741 improves omrporttest.

[knn-k]

PR #6742 fixes a failure with sysinfo in omrporttest.

[knn-k]

I see socket failures with omrporttest on AArch64 Mac, which look the same as Issue #6516 on Intel Mac.

I reviewed and merged PR #6760.
The latest test result (https://ci.eclipse.org/omr/job/PullRequest-osx_aarch64/18/) looks like this:

[2022-10-12T06:02:15.447Z] The following tests FAILED:

[Akira1Saitoh]

#6761 improves compilertest.

[knn-k]

#6763 resolved the failure with JitBuilderTest.

[knn-k]

I opened two fixes: #6792 (normalizeNaN) and #6793 (unordered fcmp/dcmp)

[knn-k]

PR #6793 was merged, and now comptest finishes without SIGTRAP caused by the assertion failure.
The remaining comptest failures are with FloatIfCompare/DoubleIfCompare (Issue #6790).

[knn-k]

All the fvtest failures on AArch64 macOS have been resolved, except for the intermittent failure with sockets (#6516).
Closing this issue.
