[Bug optimization/13850] [tree-ssa] Fails to compile ffmpeg on x86: can't find a register in class `GENERAL_REGS' while reloading `asm'

Really the code should not be using inline-asm but that is different story.  I think the problem is 
that the tree-ssa is finding some common sub expressions and combining them which is causing 
reload (the register spiller) to fail to find registers/offsets for the contstraints.
