- Re-apply 52748 and friends with fix. GetConstantStringInfo() returns an empty string for ConstantAggregateZero case which surprises selectiondag.
...
- Correctly handle memcpy from constant string which is zero-initialized.

Because of the laziness, the required passes must exist even after

LoopVR::runOnFunction runs.
This should accomplish that, but it doesn't. I think that's a PassManager bug,
but without a consumer of LoopVR in the tree, I can't give steps to reproduce.

Revert (52748 and friends):
...
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.
This unbreaks llvm-gcc bootstrap.
