  Log Message:
  -----------
  AMDGPU: Stop inferring amdgpu-agpr-alloc on irrelevant targets

This only matters for subtargets with configurable AGPR allocation.

    R llvm/test/CodeGen/AMDGPU/amdgpu-attributor-no-agpr.ll

  Log Message:
  -----------
  AMDGPU: Render non-0 values for amdgpu-agpr-alloc

This now tries to compute a lower bound on the number of registers
for individual inline asm uses. Also starts using AACallEdges
to handling indirect calls.
