59858cf792 Change the assembly syntax for nsw, nuw, and exact, putting them 
after their associated opcodes rather than before. This makes them
a little easier to read.

d1319ef308 Remove Value::setName(const char*). 
- Split into a separate patch because there is a slight functionality change,
   it is no longer valid to call setName(0), which was equivalent to
   setName(""). I'm hoping no one depends on this...

6316fbcb04 Convert StringMap to using StringRef for its APIs. 
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

7cf12c7efd reimplement Constant::ContainsRelocations as 
Constant::getRelocationInfo(), which has a much simpler
to use API.  It still should not be part of libvmcore, but
is better than it was.  Also teach it to be smart about 
hidden visibility.

f241174421 Revert the addition of hasNoPointerOverflow to GEPOperator. 
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

3d10a5a757 Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.
