[SSAF] Fix stage-2 clang build error on TestTransformationPlugin
The plugin code defines the extern variable
SSAFTestTransformationAnchorSource, which is supposed to be used to
force static linking, so not needed here.
The variable definition should undoubtedly be removed, as doing so
solves the build issue locally. The explanation below regarding why
this variable causes the issue was provided by Claude. I repeatedly
asked Claude questions, and he revised his reasoning several times
until it became consistent. However, we should still take the
following explanation with a grain of salt:
ASan created a private alias symbol for the extern variable
SSAFTestTransformationAnchorSource. The linker, when in
'-flat_namespace' mode, treated the symbol as a name-based bind, which
later failed to be resolved through name searching by the loader.

[mlir][IR] Require inherent symbol attributes for Symbol operations (#218920)
Require SymbolTable operations to implement SymbolOpInterface and store
symbol names and visibility as inherent attributes.
Add missing symbol properties/interfaces to GPU, OpenACC, OpenMP, EmitC,
and Toy operations, and update affected tests and the GPU Python
builder.

[LV] Support EVL for partial reduction and VPExpressionRecipe. (#205741)
This patch adds the support for partial reduction with EVL tail-folding
by not creating a new VPExpressionEVLRecipes but just changing the last
expressionRecipes from VPReductionRecipe to VPReductionEVLRecipe.
Currently, all partial reductions will be converted to
VPExpressionRecipe
when construction. So this patch also supports the VPExpressionRecipe
for EVL.
[BOLT][RISCV] Avoid evaluating indirect branches as direct branches (#218088)
The RISC-V branch evaluator can resolve JALR when the base register
state is known. In particular, jalr zero, zero, 0 evaluates to address
zero even though it remains an indirect branch.
Do not send indirect branches through the direct branch symbolization
path. Leave them to the existing indirect branch handling instead.
Add a regression test modeling a tail call to an undefined weak symbol
relaxed by GNU ld.
[CIR][AARCH64] Fix neon conversion test (#219069)
This fixes the neon intrinsics test, which has been failing since a
recent change to introduce more conversion handling. The test had an
inadvertantly repeated CIR check.
