  Log Message:
  -----------
  [AMDGPU] Add iglp_opt builtin and MFMA GEMM Opt strategy

Adds a builtin that serves as an optimization hint to apply specific optimized
DAG mutations during scheduling. This also disables any other mutations or
clustering that may interfere with the desired pipeline. The first optimization
strategy that is added here is designed to improve the performance of small gemm
kernels on gfx90a.
