Yaxun Liu b3d17690eb [AMDGPU] Add metadata for runtime 
Added emitting metadata to elf for runtime.

Runtime requires certain information (metadata) about kernels to be able to execute and query them. Such information is emitted to an elf section as a key-value pair stream.

Konstantin Zhuravlyov 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

Matt Arsenault 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.

Tom Stellard 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.
