Make FastEmit_ri_ try a bit harder to succeed for supported operations; FastEmit_i can fail for non-Thumb2 ARM.  Makes ARMSimplifyAddress work correctly, and reduces the number of fast-isel bailouts on non-Thumb ARM.

Filter out pattterns from the FastISel emitter which it doesn't actually know how to handle.  No significant functionality change at the moment, but it's necessary for some changes I'm planning.
