Auto merge of #102717 - beetrees:repr128-c-style-debuginfo, r=nagisa
Pass 128-bit C-style enum enumerator values to LLVM Pass the full 128 bits of C-style enum enumerators through to LLVM. This means that debuginfo for C-style repr128 enums is now emitted correctly for DWARF platforms (as compared to not being correctly emitted on any platform). Tracking issue: #56071
