Split up ARM LowerShift function.
This function was being called from two different places for completely unrelated reasons. During type legalization, it was called to expand 64-bit shift operations. During operation legalization, it was called to handle Neon vector shifts. The vector shift code was not written to check for illegal types, since it was assumed to be only called after type legalization. Fixed this by splitting off the 64-bit shift expansion into a separate function. I don't have a particular testcase for this; I just noticed it by inspection. llvm-svn: 119738
