Rework the routines that convert AP[S]Int into a string. Now, instead of
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.
