Also, make this optz'n apply in more cases where it's safe to do so.

returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

Migrate GRState::ConstEqTy (map used from tracking constants for symbols) to use the generic data map instead.

Added GRStateTrait.h, which includes boilerplate code for creating specializations of GRStateTrait<>.
Modified GRStateTrait<ConstNotEq> in GRState to use the boilerplate in GRStateTrait<> for ImmutableMaps.

Switch to shared raw_ostream code instead of having it be clang specific.
This also helps the eventual distcc project.

can *only* output data (no seeking, reading, etc).  This is adapted from the
clang "-E outputter", and is roughly 10% faster than stdio on darwin and 30%
(or more) faster than std::ostream.
