f7da4e939f Fix for PR929. The PHI nodes were being gone through for each instruction
in a successor block for every block...resulting in some O(N^k) algorithm
which wasn't very good for performance. Calculating this information up
front and keeping it in a map made it much faster.

de65fb3a8b Now that ConstantBool::True/False are gone, we can modify Type.cpp to
eliminate its static dtors, without having code that depends on order of
initialization.  Eliminate static ctors/dtors from Type.cpp.

02569d7355 - Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI just
before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.
- Modified comments. It's important to note the order of registers in the array
returns by getCalleeSaveRegs() determines the order of callee save spill code.
