[AArch64][GlobalISel] Fix nonterminating legalization for <8 x s4> vectors. (#192747)
G_CONCAT_VECTORS with <16 x s4> sources hits the bitcast legalization
path, which round-trips through scalar types (e.g. s32) and regenerates
<8 x s4> vectors via G_UNMERGE_VALUES and G_BUILD_VECTOR. The
G_BUILD_VECTOR is then widened to <8 x s8> (via .minScalarOrElt(0, s8)),
producing G_ANYEXT/G_TRUNC artifact pairs. The artifact combiner folds
these pairs away, restoring the original <8 x s4> types, which feeds
back into G_CONCAT_VECTORS again.
This change:
* Adds .minScalarOrElt(1, s8) to the G_ICMP rules to ensure operand
vector elements are at least s8. This causes <16 x s4> operands to be
widened
to <16 x s8>, and the result type follows via minScalarEltSameAs.
* Add custom legalization for G_CONCAT_VECTORS when element size < 8.
The custom handler widens source operands via G_ANYEXT (e.g.
<8 x s4> -> <8 x s8>), concats the widened vectors (producing a

[flang] NameUniquer helper for detecting module-scope data (#192733)
Add NameUniquer::isModuleScopeDataUniquedName to detect uniqued names
for module-scope data (variables, named constants, and common blocks),
excluding procedures and other prefixed symbols.
[InstCombine] Fold bitcast into vp.load (#192173)
Similar to normal loads, we should be able to fold bitcast into
`vp.load` if (1) mask is all-ones (2) either the new vector type has a
larger known minimum length than that of the original vector, or you
need to make sure the original EVL can be exact divided by the
decreasing factor (of the known minimum length).
This patch adds such folding pattern, though it only support cases where
the new vector type has a larger known minimum length.

[CIR] Fix typeinfo linkage and comdat (#192721)
We weren't properly setting the linkage on typeinfo objects, leading to
multiple definition linking error when typeinfo for a class was
referenced in multiple source files. We had the correct linkage
available in the buildTypeInfo function, but we weren't doing anything
with it. This also prevented us from hitting the diagnostic saying that
we should have set the comdat attribute for the typeinfo. This change
fixes both of those problems.

[lldb] Fix TestThreadExit.py flakiness (#190976)
When `pthread_join` returns, the target thread signals its internal
semaphore, but the underlying Mach thread hasn't been removed from the
task yet with `thread_terminate`.
The flakiness is the result of the debugger stopping the process halts
the dying thread mid-termination. There is no Mach API to distinguish a
dying thread from a live one: it appears as `TH_STATE_STOPPED`, like any
other suspended thread.
This PR adds a helper (`wait_for_thread_cleanup`) that polls
`task_threads` to ensure the Mach thread is actually gone before the
breakpoint. Since there might be other tests that are affected by this
race, I put it in a common location so it can be reused.
