f16d8ade4f Change raw_fd_ostream to take flags as an optional bitmask 
instead of as two bools.  Use this to add a F_Append flag
which has the obvious behavior.

Other unrelated changes conflated into this patch:

1. REmove EH stuff from llvm-dis and llvm-as, the try blocks
   are dead.
2. Simplify the filename inference code in llvm-as/llvm-dis,
   because raw_fd_ostream does the right thing with '-'.
3. Switch machine verifier to use raw_ostream instead of ostream
   (Which is the thing that needed append in the first place).

b20aefd460 add a raw_ostream::indent method, to be used like: 
OS.indent(i) << "whatever";

people seem to like indenting things ;-)

115971f6a7 Change raw_svector_ostream to reserve the input buffer if necessary, Ted was 
right.
 - This class turns out to be much more convenient to use if we do this; clients
   can make sure the buffer is always big enough if they care (since our current
   idiom tends to be to use a SmallString<256> for the input to this we should
   generally be avoiding an unnecessary malloc).

Also, add a convenience raw_svector_ostream::str method which flushes the buffer
and returns a StringRef for the vector contents.

2e2969f9e1 Switch raw_svector_ostream to use the vector as the ostream buffer. 
- This avoids unnecessary malloc/free overhead in the common case, and
   unnecessary copying from the ostream buffer into the output vector.

85b15d8e71 raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation. 
- Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

1d84247c99 Fix a bug in raw_ostream::write(char) introduced by the change to 
allow underlying stream classes to decline buffering. After
calling SetBuffered(), re-check whether the stream is Unbuffered
in order to handle the case where the underlying stream has
declined buffering.

0c10b8864a When standard output is a terminal, set outs() to be unbuffered, to 
mimic the behavior of stdtout, which is line-buffered when the output
is a terminal. This fixes some issues with bugpoint output appearing
