Add openmp test to xfail list
Introduced in PR #219323. Looking at the PR, and given we haven't yet addressed openmp profcheck failures, the change is highly unlikely to have introduced a new regression (it's exposing existing ones)
[OpenMPOpt] Bound indirect-call specialization instead of paying for all of it (#219323)
`registerAAsForFunction()` seeds `AAIndirectCallInfo` unconditionally,
so device
code pays for specializing every indirect call site. Device code routes
many
calls through function-pointer tables and virtual dispatch, so a call
site can
see every address-taken candidate in the module, and the if-cascade
`AAIndirectCallInfo` builds over them is quadratic.
Skip specialization at a call site with more than three possible
callees,
overridable with `-openmp-opt-max-callees-for-specialization`. The bound
is a
threshold on the call site rather than a limit on how many callees get
specialized: the Attributor asks about each callee with the same total,
so a
site above the threshold keeps its indirect call instead of getting

[CIR][CMake] Configure MLIR as a dependency-only project
ClangIR requires MLIR, but enabling CIR currently requires users to list MLIR
explicitly in LLVM_ENABLE_PROJECTS. That also attaches all MLIR build, install,
unit-test, and lit targets to the corresponding LLVM aggregates.
When Clang is selected and CLANG_ENABLE_CIR is enabled, append MLIR to the
effective LLVM_ENABLE_PROJECTS list. The common project setup compares that
list with the cached user selection, so an explicit MLIR selection retains its
normal behavior while an implicit selection is configured with EXCLUDE_FROM_ALL.
This makes MLIR targets available for CIR dependency resolution without adding
MLIR's aggregate targets. Keep the existing standalone ClangIR restriction and
do not configure MLIR when CIR is disabled.
Validation:
- Configured Clang with CIR and implicit MLIR test support.
- Configured Clang and MLIR explicitly with CIR and tests enabled.
- Configured Clang without CIR and verified that MLIR remains disabled.

[CMake] Infer dependency-only projects from the cache
LLVM_ENABLE_PROJECTS historically treats projects enabled to satisfy another
project's dependency the same as projects selected by the user. Consequently,
implicit projects attach their complete build, install, and test suites to
LLVM's aggregate targets.
Keep the cache entry as the user-requested project roots and use the normal
LLVM_ENABLE_PROJECTS variable as the effective dependency closure. Projects in
the effective list but not the cache entry are configured with EXCLUDE_FROM_ALL.
Normalize the special all value before comparing the two sets.
This makes Flang's MLIR and Clang dependencies dependency-only without a second
project collection. It also applies the same rule to Clang when it is added for
LLDB. Forward the cached roots to cross-compilation and bootstrap configurations
so implicit projects do not become explicit in nested builds.
Let MLIR own its dependency-only test policy: configure test support libraries
for downstream consumers without creating MLIR unit tests or registering its

[CIR] Implement PromotableRegionOpInterface for cir.scope
Same treatment as cir.if: a slot read inside a cir.scope no longer needs
the CFG flattened before mem2reg can promote it. The scope region is
entered directly from before the operation, so it sees the reaching
definition unchanged.
cir.scope yields at most one value and may already be using it for the
scope's own result, so regions that store to the slot are refused.

[CIR] Implement PromotableRegionOpInterface for cir.if
mem2reg gives up on a memory slot as soon as one of its uses lives in a
nested region whose parent op does not implement
PromotableRegionOpInterface. Since no CIR op implements it, promoting a
slot read inside a cir.if required running cir-flatten-cfg first, which
is why clang/test/CIR/Transforms/mem2reg.cir has to flatten before it can
promote anything.
Implement the interface for cir.if. Both regions are entered directly
from before the operation, so both see the same reaching definition.
A definition created inside a region has to leave the operation through
one of its results, and cir.if has none, so isRegionPromotable refuses
regions that store to the slot. Supporting those requires giving cir.if
results and is left for later.
