fad86b003a 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.

60d3962624 add a new raw_ostream class which is an extremely high performance ostream that
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.

fe24bd3a89 Add a NullFolder class that doesn't fold constants.
This may be used as the second IRBuilder template
parameter, the idea being that people learning LLVM
may find it helpful (several people asked on IRC
if it was possible to turn off constant folding
because it made it hard for them to see what was
going on).  Compiles, but otherwise completely
untested.

1e7f7865eb Make it possible to use different constant
folding policies with IRBuilder.  The default,
provided by ConstantFolder, is to do minimal
folding like now: what ConstantExpr provides.
An alternative is to use TargetFolder, which
uses target information to fold constants more.
