Subject: [PATCH] [CIR][CodeGen] Share isStandardLibraryRTTIDescriptor
Deduplicates `isStandardLibraryRTTIDescriptor` between CIR and classic CodeGen,
taking the classic implementation. CIR's copy hit `llvm_unreachable("NYI")` on
`WasmExternRef` and `HLSLResource`; neither is reachable in CIR today, so no
test changes.
