Refactor the pass to only support `IntrinsicInst` calls.
`ReplaceWithVecLib` used to support instructions, as AArch64 was using
this pass to replace a vectorized frem instruction to the fmod vector
library call (through TLI).
As this replacement is now done by the codegen (#83859), there is no
need for this pass to support instructions.
Additionally, removed 'frem' tests from:
- AArch64/replace-with-veclib-armpl.ll
- AArch64/replace-with-veclib-sleef-scalable.ll
- AArch64/replace-with-veclib-sleef.ll
Such testing is done at codegen level:
- #83859
It appears that Google Tests run multiple modules from the same
invocation.
As a result setting `llvm::DebugFlag` in this pass kept it on in
subsequent passes, which is not the expected behavior.
Fix a crash of `replace-with-veclib` pass, when the arguments of the TLI
mapping do not match the original call.
Now, it simply ignores such cases.
Test require assertions as it accesses programmatically the debug log.
