Disabling the pre-RA scheduler on large-work-group-registers
causes it to be ~50% slower.

Nicolai Haehnle d791bd07c7 AMDGPU: Release the scavenged offset register during VGPR spill
Summary:
This fixes a crash where subsequent spills would be unable to scavenge
a register. In particular, it fixes a crash in piglit's
spec@glsl-1.50@execution@geometry@max-input-components (the test still
has a shader that fails to compile because of too many SGPR spills, but
at least it doesn't crash any more).

This is a candidate for the release branch.
