5d8f1a58b3 Improve the description on the getelementptr instruction. It should now better 
define what the instruction does. This also makes it clear that getelementptr
can index into a vector type.

1ea1008e1f * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns 
null. This assumes that any target that does not have AsmInfo, does not
   support "LocAndDot".

ed4cd79ffc 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.

d724368eeb Duncan convinced me that it's not possible to transform control-based escapes into 
data-based ones.  Just be conservative when analyzing control-based escapes.

a couple other cases for clarity, but shouldn't affect correctness.

the same pattern as roundpd/roundps, the Intel compiler 
builtins do not:  rounds* has an extra operand.  Fixes
