Remove this hard-coded buffer size. In some basic experiments preprocessing
...
large files, this doesn't seem significantly better than just letting
raw_ostream pick a buffer size.
This code predates raw-ostream's automatic buffer sizing; in fact, it
was introduced as part of the code which would eventually become
raw_ostream.

The JIT calls TidyLandingPads to tidy up the landing pads. However, because the
...
JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
section for the MCSymbol is never set. And thus the MCSymbol for the EH label
isn't marked as "defined". Because of that, TidyLandingPads removes the needed
landing pads from the JIT output. This breaks EH for every JIT program.
This is a work-around for this limitation. We pass in the label locations
map. If the label has a non-zero value, then it was "emitted" by the JIT and
TidyLandingPads shouldn't remove that label.
A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
upon the section being set to determine if it's defined or not.
