History

Jakob Stoklund Olesen 9cda1be0aa Prioritize smaller register classes for urgent evictions.

It helps compile exotic inline asm. In the test case, normal GR32
virtual registers use up eax-edx so the final GR32_ABCD live range has
no registers left. Since all the live ranges were tiny, we had no way of
prioritizing the smaller register class.

This patch allows tiny unspillable live ranges to be evicted by tiny
unspillable live ranges from a smaller register class.

Switch the canonical FMA term operand order to match both the comment I wrote and the usual LLVM convention.
