[X86][SSE] Add support for extending bool vectors bitcasted from scalars

This patch acts as a reverse to combineBitcastvxi1 - bitcasting a scalar integer to a boolean vector and extending it 'in place' to the requested legal type.

Currently this doesn't handle AVX512 at all - but the current mask register approach is lacking for some cases.
