This is a hack until I come up with a better way of dealing with the pseudo-register banks used for boolean values. If the use instruction constrains the register, the selector for the def instruction won't see that the bank was VCC. A 1-bit SReg_32 is could ambiguously have been SCCRegBank or VCCRegBank in wave32. This is necessary to successfully select branches with and and/or/xor condition. llvm-svn: 366120
