Add a pass to lower is.constant and objectsize intrinsics This pass lowers is.constant and objectsize intrinsics not simplified by earlier constant folding, i.e. if the object given is not constant or if not using the optimized pass chain. The result is recursively simplified and constant conditionals are pruned, so that dead blocks are removed even for -O0. This allows inline asm blocks with operand constraints to work all the time. The new pass replaces the existing lowering in the codegen-prepare pass and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert on the intrinsics.

This directory contains bindings for the LLVM compiler infrastructure to allow programs written in languages other than C or C++ to take advantage of the LLVM infrastructure--for instance, a self-hosted compiler front-end.
