7e6d9b96ad Make InstructionCombining::getBitCastOperand() recognize GEP instructions and 
constant expression with all zero indices as being the same as a bitcast.

d9d07780ff * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns 
null. This assumes that any target that does not have AsmInfo, does not
   support "LocAndDot".

cb8f1b5b8b Disallow the construction of SCEVs with could-not-compute operands. Catch CNCs 
returned by BinomialCoefficient and don't try to operate with them. This
replaces the previous fix for PR2857.

data-based ones.  Just be conservative when analyzing control-based escapes.

43d9c8cd56 Use template to distinguish between function variants. 
GCC 4.4.0 gives an error on the "int" declaration for example
saying that it has already been declared (using the "short"
one). Using templates here allow the compiler to distinguish
between the function to choose.

Also, "llvm/Support/DataTypes.h" was not included, leading to
error messages about not knowing "uint32_t" for example.

Patch by Samuel Tardieu.
