Add back the capability to include nul characters in strings with
...
GetConstantStringInfo. This will hopefully restore llvm-gcc to
happy bootstrap land.

fix the regressions from Eric's patch by making GetConstantStringInfo
...
tolerate a non-nul-terminated string, and handling a direct global
reference.

Move GetConstantStringInfo to lib/Analysis. Remove
...
string output routine from Constant. Update all
callers. Change debug intrinsic api slightly to
accomodate move of routine, these now return values
instead of strings.

Make the InsertBefore argument to FindInsertedValue optional, so you can find an inserted value without modifying the code.

Move FindScalarValue from InstructionCombining.cpp to ValueTracking.cpp. While
...
I'm at it, rename it to FindInsertedValue.
The only functional change is that newly created instructions are no longer
added to instcombine's worklist, but that is not really necessary anyway (and
I'll commit some improvements next that will completely remove the need).

ComputeNumSignBits about the number of sign bits in a constantint.
