148d3bb9b4 Reapply 74494, this time removing the conflicting definition of operator<< 
in APIntTest.cpp.

f207911974 Define an operator<< for APInt to be used with std::ostream. 
This will allow it to be used in unittests that use gtest's
EXPECT_EQ.

c934b656f9 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.

366006cfd3 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.

09cab2de98 fix overflow checks in SmallVector: 
"The code was doing "if (End+NumInputs > Capacity) ...". If End is
close to 0xFFFFFFFF and NumInputs is large, it'll overflow, the
condition will come out false, and the vector won't grow to
accommodate the new elements, and the program will crash in memmove."

588d3d1fd6 Add llvm::Triple class for abstracting access to target triples. 
- The code is silly, I'm just amusing myself. Rewrite to be efficient
   if you like. :)

Also, if you wish to debate the proper names of the triple components
I'm all ears.
