[X86][AVX] combineBitcastvxi1 - peek through bitops to determine size of original vector

We were only testing for direct SETCC results - this allows us to peek through AND/OR/XOR combinations of the comparison results as well.

There's a missing SEXT(PACKSS) fold that I need to investigate for v8i1 cases before I can enable it there as well.

The LLVM Compiler Infrastructure

This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments.
