We correctly reject that. GAS has a bug when processing instructions like
"movsx (mem), %rax".  The instruction doesn't specify a size (it could
reasonably be 8 bits, 16 bits, or 32-bits) so gas just picks a random one.  It
is better for llvm to reject it and force projects to make their assumptions
