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, conflicts will be resolved prior to merging.
