This revision is now accepted and ready to land.

This patch survives several tests from llvm-test-suite in `O0` build which otherwise report errors like:

  fatal error: error in backend: Error while trying to spill R7 from class GPR: Cannot scavenge register without an emergency spill slot!

These tests includes:

- MultiSource/Benchmarks/mafft
- SingleSource/Regression/C/gcc-c-torture/execute/multi-ix.c
- SingleSource/UnitTests/matrix-types-spec.cpp
