Fix some unnoticed/unwanted behavior change from r222319. The ARM assembler allows register alias redefinitions as long as it targets the same register. r222319 broke that. In the AArch64 case it would just produce a new warning, but in the ARM case it would error out on previously accepted assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228109 91177308-0d34-0410-b5e6-96231b3b80d8 2015-02-04 03:10:03 +00:00			`@ The line is duplicated on purpose, it is legal to redefine a req with`
