Konstantin Zhuravlyov f4ace63737 AMDGPU: Add target id and code object v4 support 
- Add target id support (https://clang.llvm.org/docs/ClangOffloadBundler.html#target-id)
  - Add code object v4 support (https://llvm.org/docs/AMDGPUUsage.html#elf-code-object)
    - Add kernarg_size to kernel descriptor
    - Change trap handler ABI to no longer move queue pointer into s[0:1]
  - Cleanup ELF definitions
    - Add V2, V3, V4 suffixes to make a clear distinction for code object version
    - Consolidate note names

Ronak Chauhan e760e85680 [llvm-objdump][AMDGPU] Detect CPU string 
AMDGPU ISA isn't backwards compatible and hence -mcpu must always be specified during disassembly.
However, the AMDGPU target CPU is stored in e_flags in the ELF object.

This patch allows targets to implement CPU string detection, and also implements it for AMDGPU by looking at e_flags.
