3. The tests in riscv-arch.c will show default arch changes for abi=ilp32,

In a framework Foo.framework, Foo.framework/Foo is usually a relative
symbolic link to Foo.framework/Versions/Current/Foo,
and Foo.framework/Versions/Current is usually a relative symbolic
link to A.

Our tests used absolute symbolic links. Now they use relative symbolic links.

No behavior change, just makes the tests more representative of the real world.

(implicit-dylib.s omits the "Current" folder too, but I'm not changing that
here.)

This is important for Frameworks, which are usually symlinks.

ld64 gets this right for @rpath that's replaced with @loader_path, but not for
bare @loader_path -- ld64's code calls realpath() in that case too, but ignores
the result.

ld64 somehow manages to find libbar1.dylib in the test without the
explicit `-rpath` in Foo1. I don't understand why or how. But this
change is a step forward and fixes an immediate problem I'm having,
so let's start with this :)

A common mistake for newcomers to MLIR is to try to store extra member
on the Op class. However these are intended to be thing wrapper around
an Operation*, all the storage is meant to be encoded in attribute on
the underlying Operation. This can be confusing to debug, so better
catch it at build time.

Packed_A must be copied repeatedly, not just for the first iteration of

This fixes llvm.org/PR50557

Summary:
The current implementation of AANoFreeFloating will incorrectly list floating
point loads and stores as may-free. This prevents other attributor instances

[compiler-rt][hwasan] Decouple use of the TLS global for getting the shadow base and using the frame record feature

This allows for using the frame record feature (which uses __hwasan_tls)
independently from however the user wants to access the shadow base, which
prior was only usable if shadow wasn't accessed through the TLS variable or ifuncs.

Frame recording can be explicitly set according to ShadowMapping::WithFrameRecord
in ShadowMapping::init. Currently, it is only enabled on Fuchsia and if TLS is
used, so this should mimic the old behavior.

Added an extra case to prologue.ll that covers this new case.
