use the new form of getNameWithPrefix, not makeNameProper.

Among other things, this would do very weird things if the
basic block name had (e.g.) a space in it on darwin:
makeNameProper would add quotes, then the mcsymbol would
escape the quotes.

change Mangler::makeNameProper to return its result in a SmallVector
...
instead of returning it in an std::string. Based on this change:
1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
prefixes, not use temporary std::strings, and to avoid other crimes.

Add a quick pass to optimize sign / zero extension instructions. For targets where the pre-extension values are available in the subreg of the result of the extension, replace the uses of the pre-extension value with the result + extract_subreg.
...
For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

2) When cloning blocks for PHI or xor conditions, use
instsimplify to simplify the code as we go. This allows us to
