[X86][SSE] Use MOVMSK for all_of/any_of reduction patterns
This is a first attempt at using the MOVMSK instructions to replace all_of/any_of reduction patterns (i.e. an and/or + shuffle chain). So far this only matches patterns where we are reducing an all/none bits source vector (i.e. a comparison result) but we should be able to expand on this in conjunction with improvements to 'bool vector' handling both in the x86 backend as well as the vectorizers etc. Differential Revision: https://reviews.llvm.org/D28810 llvm-svn: 293880
