Jakob Stoklund Olesen 1e3aeefc08 VirtRegRewriter checks for early clobbers before it reuses an available stack
slot.

Teach it to also check for early clobbered aliases, and early clobber operands
following the current operand.

This fixes the miscompilation in PR8044 where EC registers eax and ecx were
being used for inputs.
