16d027ce3e Be more aggressive in the heuristic. This mostly exposes more opportunities 
for the GVN part of GVNPRE to apply.

d50fe47cf3 Achieve what the incorrect test was trying to do by simply requiring that all 
critical edges be split before we begin.

f926a3080c The exception handling intrinsics return values, 
so must be lowered to a value, not nothing at all.
Subtle point: I made eh_selector return 0 and
eh_typeid_for return 1.  This means that only
cleanups (destructors) will be run as the exception
unwinds [if eh_typeid_for returned 0 then it would
be as if the first catch always matched, and the
corresponding handler would be run], which is
probably want you want in the CBE.

f5e225a756 eliminate residual cruft related to recognizing bytecode 
files.
bitcode files are the only LLVM format left.

404336eb55 Indexes into the list of filter ids cannot be output 
directly: they need to be turned into byte offsets
(often the same, but may not be if there are many
type infos).

90c6b87b31 Add a parameter to getCopyToParts and getCopyFromParts to specify whether 
endian swapping should be done, and update the code to use it. This fixes
some register ordering issues on big-endian systems, such as PowerPC,
introduced by the recent illegal by-val arguments changes.

eca2fa295b Make sure only one copy of a filter is placed in the 
exception handling table if we encounter it multiple
times.  Filters could be folded harder than this, but
that would mean a lot more work for not much gain.
