Tentatively merge llvm fix for buildworld WITH_ASAN
Building world using WITH_ASAN results in an assertion when compiling
certain source files referencing ifuncs:
Assertion failed: (isa<Function>(Callee) || isa<GlobalAlias>(Callee)), function analyzeAllUses, file /root/freebsd/contrib/llvm-project/llvm/lib/Analysis/StackSafetyAnalysis.cpp, line 514.
This was already reported upstream a while ago, in
<https://github.com/llvm/llvm-project/issues/87923>, but now there is
finally a candidate fix, which seems trivial so I am importing it right
away.
