Fix handling of overflow in loop calculation by adding new UDiv SCEV. This SCEV
...
is disabled in the sense that it will refuse to create one from a UDiv
instruction, until the code is better tested.

Rename ScalarEvolution::deleteInstructionFromRecords to
...
deleteValueFromRecords and loosen the types to all it to accept
Value* instead of just Instruction*, since this is what
ScalarEvolution uses internally anyway. This allows more flexibility
for future uses.

Use 'static const char' instead of 'static const int'.

Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Added an automatic cast to "std::ostream*" etc. from OStream. We then can
...
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.
