[FuncSpec] Conditional jump or move depends on uninitialised value(s).
I found this bug when performing a two-stage build of clang with
Function Specialization enabled and tuned aggressively. The crash
appears only on release builds.
Fixes https://github.com/llvm/llvm-project/issues/55000.
Before accessing the contents of the ArgInfo iterator inside
SCCPInstVisitor::markArgInFuncSpecialization, we should be
checking that the iterator is valid.
