Add a bit to mark operands of asm's that conflict
with an earlyclobber operand elsewhere. Propagate this bit and the earlyclobber bit through SDISel. Change linear-scan RA not to allocate regs in a way that conflicts with an earlyclobber. See also comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56290 91177308-0d34-0410-b5e6-96231b3b80d8
