This feature is only relevant to shaders, and is no longer used. When disabled,
lowering of reserved registers for shaders causes a compiler crash.
Remove the feature and add a test for compilation of shaders at OptNone.

This switches to the workaround that HSA defaults to
for the mesa path.
This should be applied to the 4.0 branch.

Summary:
Without the fix to isFrameOffsetLegal to consider the instruction's
immediate offset, the new test case hits the corresponding assertion in
resolveFrameIndex, because the LocalStackSlotAllocation pass re-uses a
different base register.
With only the fix to isFrameOffsetLegal, code quality reduces in a bunch of
places because frame base registers are added where they're not needed.
This is addressed by properly implementing needsFrameBaseReg, which also
helps to avoid unnecessary zero frame indices in a bunch of other places.
