Add llvm_start_multithreaded(), which starts up the LLVM internals in thread-safe mode.  Provide double-check locking
initialization of ManagedStatic's when running in thread-safe mode.

Also, if you wish to debate the proper names of the triple components
I'm all ears.

of places know about this; I think I got them all.

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.

 - 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.

large for the testsuite) took over six minutes to compile on my Mac.
The patched LLVM-GCC compiles that testcase in three seconds (GCC
takes less than one second).  This hash function is more complex
(about 35 instructions on x86) than what Chris wanted, but I expect it
will be well-behaved with arbitrary inputs.

Thank you to everyone who responded to my previous request for advice.
