2f8cc26be4 remove uses of deprecated functions, this generates slightly 
different BlockAddress labels, but nothing semantically important.

Add a FIXME that BlockAddress codegen is broken if the LLVM BB has 
an empty name (e.g. strip was run).

dfbcb8c38b 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.

bf86e5df18 add new isSingleStringRef()/getSingleStringRef() methods to twine, 
and use them to avoid a copy of a string in getNameWithPrefix in
the common case.  It seems like Value::setName and other places 
should use this as well?

0e7ab8cb07 ugh, my last patch just sped up a method and changed all the clients 
that I want to completely eliminate.  Add fixme's so I remember this
in the future, and add the missing helper that they should be upgraded
to use instead.

4813035b72 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.

c5b7ef1519 Remove the JustSP single-register regclass.

and that is pattern matched in a way that guarantees SP is used. There is
never any register allocation done from this class.

7da9ecf967 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.
