Subject: [PATCH 1/3] [IPSCCP] Variable not visible at Og:
https://bugs.llvm.org/show_bug.cgi?id=51559
https://github.com/llvm/llvm-project/issues/50901
IPSCCP pass removes the global variable and does not
create a constant expression for the initializer value.
Extend test coverage to include:
- half and bfloat types.
- checks for undef (int32 and ptr).

IPSCCP pass removes the global variable and does not

Fix assertion detected by the BuildKite pre-commit CI:
llvm::APInt::getZExtValue() const:
`getActiveBits() <= 64 && "Too many bits for uint64_t"' failed.
