Add lowering support for llvm.experimental.deoptimize Summary: Only adds support for "naked" calls to llvm.experimental.deoptimize. Support for round-tripping through RewriteStatepointsForGC will come as a separate patch (should be simpler than this one).

MCStreamer: Use "cfi" for CFI related temp labels. Choosing a "cfi" name makes the intend a bit clearer in an assembly dump and more importantly the assembly dumps are slightly more stable as the numbers don't move around anymore when unrelated code calls createTempSymbol() more or less often. As they are temp labels the name doesn't influence the generated object code. Differential Revision: https://reviews.llvm.org/D27244 llvm-svn: 288290

[StackMaps] Increase the size of the "location size" field Summary: In some cases LLVM (especially the SLP vectorizer) will create vectors that are 256 bytes (or larger). Given that this is intentional[0] is likely to get more common, this patch updates the StackMap binary format to deal with the spill locations for said vectors. This change also bumps the stack map version from 2 to 3.
