ab2419e712 give StringMap a new ctor which allows you to initialize it 
with an existing allocator.  The interesting use case of this
is that it allows "StringMap<whatever, BumpPtrAllocator&>" for
when you want to allocate out of a preexisting bump pointer
allocator owned by someone else.

93b617fac4 Add a method to get a StringMapEntry from a pointer to the string 
data it contains (similar to GetStringMapEntryFromValue).

b5adc13728 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.

49498bdff4 fix a pretty serious bug in StringMap where GetOrCreate(strstart,strend, z) 
would not set new values to Z.

71f808dfa2 * Don't explicitly cast "0" to "void*". This doesn't work well with specialized 
StringMapEntryInitializer classes. Leave it for the compiler to figure out what
 the type is and what "0" should be transformed into.

* Un-disable the unit tests which test the StringMapEntryInitializer class.
