This adds infrastructural pieces for an analysis to compute the DXIL
shader flags. In this state the analysis can compute two fairly
straightforward feature flags for use of double-precision floating
point values and the DX 11.1 extended double support.

This patch does conflict with D135190 <https://reviews.llvm.org/D135190>, conflicts will be resolved prior
to merging.
