de75d7ffcd Add slow path for single character write, and use exclusively for
single characters writes outside of the fast path in raw_ostream.h

bcf8ea9554 raw_ostream: unbuffered streams weren't being immediately flushed on

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

3d4866e683 Added "str()" method to raw_string_ostream.
str() mirrors the same method in std::ostringstream.
str() flushes the buffered stream contents to string and returns a reference to the string.

944fac71e0 Switch the asmprinter (.ll) and all the stuff it requires over to
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.

097af7fc8f add a simple mechanism for formatted output. This gives raw_ostream's
all the power and risk of fprintf format strings.  Use them like this:

  OS << format("%10.4f", 42.0) << "\n" << format("%x", 42) << '\n';

89a1a85913 Implement operator<< in terms of basic types rather than [u]int*_t, which is better for portability. There might be some way to factor this all with metaprogramming magic, but I'm not sure how offhand.

the suggestion of resistor.

If this breaks some other platform, please go ahead and back this out.

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.
