A few inline asm cleanups:
- Make targetlowering.h fit in 80 cols. - Make LowerAsmOperandForConstraint const. - Make lowerXConstraint -> LowerXConstraint - Make LowerXConstraint return a const char* instead of taking a string byref. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50312 91177308-0d34-0410-b5e6-96231b3b80d8
