69e6a8d5a8 Make the clobber analysis a bit more smart: we only are careful about
early clobbers if the clobber list contains a *register* not some thing
like {memory}, {dirflag} etc.

0fe71e9bb1 Treat clobber operands like early clobbers: if we have
any, we force sdisel to do all regalloc for an asm.  This
leads to gross but correct codegen.

This fixes the rest of PR2078.

7cbeb2431c Fix a (harmless) but where vregs were added to the used reg lists for
inline asms.

Fix PR2078 by marking aliases of registers used when a register is 
marked used.  This prevents EAX from being allocated when AX is listed
in the clobber set for the asm.

c927cc8731 Remove one of the fixmes that I put in there. From Evan:
No need to go up more levels. A def of a register also sets its sub-registers
(so if PhysRegInfo[SuperReg] is NULL, it means SuperReg's super registers are
not previously defined).
