scott.linder added a parent revision: D74914: Clean up assembler CFI directives.

Implement the DWARF register mapping described in
llvm/docs/AMDGPUUsage.rst

This is currently limited to wave64 VGPRs/AGPRs.

This also includes some minor changes in AMDGPUInstPrinter and
AMDGPUMCTargetDesc to make generating CFI assembly text and ELF sections
possible to ease testing, although complete CFI support is not yet
implemented.
