7e763ebd98 Use the RHS length instead of the LHS length. They are both the same,
but this ends up compiling code like this:

int foo(const StringRef &R) {
  return R == "food";
}

to use a constant sized memcmp instead of a variable memcmp.

a14d225ef4 Update Triple to use StringRef/Twine based APIs.
- This is now shorter, simpler, safer, and more efficient, what a deal.

f595d6dd9a Add a missing ilist_node.h #include to SparseBitVector, and add a very short
test for it. The test is by no means complete, but it tests the problem I was
fixing.

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.

- reduces _static_ callee saved register spills

- 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.
