e49d0bc946 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.

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

replaces the previous fix for PR2857.

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