LLVM generates illegal `rbit r0, #352` instruction for rbit intrinsic. According to ARM ARM, rbit only takes register as argument, not immediate. The correct instruction should be rbit <Rd>, <Rm>. The bug was originally introduced in r211057. Differential Revision: http://reviews.llvm.org/D4980 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216064 91177308-0d34-0410-b5e6-96231b3b80d8
