// AsmParser::parseRegisterOrRegisterNumber in MC implies we either emit this
// as an integer or we provide a name which represents a physical register.
// For CFI instructions we really want to emit a name for the DWARF register
// instead, because there may be multiple DWARF registers corresponding to a
// single physical register. One case where this problem manifests is with
// wave32/wave64 where using the physical register name is ambiguous: if we
// write e.g. `.cfi_undefined v0` we lose information about the wavefront
// size which we need to encode the register in the final DWARF. Ideally we
// would extend MC to support parsing DWARF register names so we could do
// something like `.cfi_undefined dwarf_wave32_v0`. For now we just live with
// non-pretty DWARF register names in assembly text.
