f2f3d14774 [AMDGPU] Emit debugger prologue and emit the rest of the debugger fields in the kernel code header 
Debugger prologue is emitted if -mattr=+amdgpu-debugger-emit-prologue.

Debugger prologue writes work group IDs and work item IDs to scratch memory at fixed location in the following format:
  - offset 0: work group ID x
  - offset 4: work group ID y
  - offset 8: work group ID z
  - offset 16: work item ID x
  - offset 20: work item ID y
  - offset 24: work item ID z

Set
  - amd_kernel_code_t::debug_wavefront_private_segment_offset_sgpr to scratch wave offset reg
  - amd_kernel_code_t::debug_private_segment_buffer_sgpr to scratch rsrc reg
  - amd_kernel_code_t::is_debug_supported to true if all debugger features are enabled

6b6a2c37bc AMDGPU: R600 code splitting cleanup 
Move a few functions only used by R600 to R600 specific code,
fix header macros to stop using R600, mark classes as final.

c93fc11f36 AMDGPU/SI: Emit constant arrays in the .text section 
Summary:
This allows us to remove the END_OF_TEXT_LABEL hack we had been using
and simplifies the fixups used to compute the address of constant
arrays.

f151a45ccd AMDGPU/SI: Emit amd_kernel_code_t in EmitFunctionBodyStart() 
Summary:
This way the function symbol points to the start of amd_kernel_code_t
rather than the start of the function.
