Analysis: Move LibcallLoweringInfo from CodeGen to Analysis Middle end passes need to be able to reason about library call availability and potentially emit them without depending on codegen. TargetLibraryInfo already lives in Analysis, and this is a step towards the eventual merger. For now this is a mostly mechanical move, type erasing the reference to TargetSubtargetInfo. The per-subtarget customization (TargetSubtargetInfo::initLibcallLoweringInfo) is inverted into a caller-supplied function_ref, so the Analysis types carry no CodeGen/TargetSubtargetInfo reference. The module map is keyed on an opaque erased pointer. CodeGen continues looking up based on the subtarget. It is not yet in a state where it is usable from middle end passes; that will come later. In principle we should be able to write arbitrary rules based on a function's ABI attributes for which calls can be used.
