a single character requires only one branch to follow slow path.
- Never use a buffer when writing on an unbuffered stream.
- Move default buffer size to header.

write as arguments.
- Add raw_ostream::GetNumBytesInBuffer.
- Privatize buffer pointers.
- Get rid of slow and unnecessary code for writing out large strings.

- Flush a known non-empty buffers; enforces the interface to
flush_impl and kills off HandleFlush (which I saw no reason to be
an inline method, Chris?).
- Clarify invariant that flush_impl is only called with OutBufCur >
OutBufStart.
- This also cleary collects all places where we have to deal with the
buffer possibly not existing.
- A few more comments and fixing the unbuffered behavior remain in
this commit sequence.

- Add unbuffered flag to raw_ostream, forwarded by raw_fd_ostream and
used by raw_stderr_ostream.

use raw_ostream instead of std::ostream. Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).
Other interesting changes:
1) This makes Value::print be non-virtual.
2) AP[S]Int and ConstantRange can no longer print to ostream directly,
use raw_ostream instead.
3) This fixes a bug in raw_os_ostream where it didn't flush itself
when destroyed.
4) This adds a new SDNode::print method, instead of only allowing "dump".
A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream
versions.
This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.

all the power and risk of fprintf format strings. Use them like this:
OS << format("%10.4f", 42.0) << "\n" << format("%x", 42) << '\n';

a simple adaptor class to give raw output capabilities to
something that wants to write to an ostream.

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.
