0fa1e2d063 Commit some changes I had managed to lose last night while refactoring the code. Avoid change use of PHI instructions because it's not legal to insert any instructions before them.

1b6c061cd0 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).

086d0d1a2b 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.

9c1ca33ac3 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?

951cfb6b8b 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.

3c2fad1fc6 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.

2d819b93a2 Remove the JustSP single-register regclass. 
It was only being used by instructions with the t_addrmode_sp addressing mode,
and that is pattern matched in a way that guarantees SP is used. There is
never any register allocation done from this class.

76db3bb18e 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.
