332a173cff avoid string thrashing when formatting names in output. This
speeds up release-asserts llvm-dis on kc++ from 1.86s to 1.04s (~79%)

dab4a64423 add support for a cout/cerr analog (outs()/errs()) as well as
a simple adaptor class to give raw output capabilities to 
something that wants to write to an ostream.

312d8de59b 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.

b5abdd4c33 The pass manager is not able to schedule -loop-deletion -loop-index-split.
The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

3bbc2deb9c Replace two for loops with while(!X->use_empty()) loops. This prevents
invalidating the iterator by deleting the current use. This fixes a segfault on
64 bit linux reported in PR2675.

Also remove an unneeded if.
