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.

8f3cfb4c65 ImmutableMap/ImmutableSet: Allow caching of ImutAVLTree digests while the tree 
is still mutable. My experiments show this reduces the amount of times we
compute a full tree digest by over 50% on very small cases, and potentially much
larger on others.

c5d73afa48 Tighten up the asserts in SmallVector::operator[](). 
If this causes any new assertion failures that I didn't catch in
testing, the fix is usually to change "&v[0]" to "v.data()" for some
SmallVector v.

b9cfbd94ab Shrink wrapping in PEI: 
- reduces _static_ callee saved register spills
  and restores similar to Chow's original algorithm.
- iterative implementation with simple heuristic
  limits to mitigate compile time impact.
- handles placing spills/restores for multi-entry,
  multi-exit regions in the Machine CFG without
  splitting edges.
- passes test-suite in LLCBETA mode.

Added contains() method to ADT/SparseBitVector.
