[fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271%
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester. This may also improve compile-time on architectures that would otherwise generate a libcall for urem (e.g., ARM) or fall back to the DAG selector. rdar://10810716 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153230 91177308-0d34-0410-b5e6-96231b3b80d8
