so that we don't break it with code changes. 

After doing this I was able to fix the POSIX-DYLD plug-in so that it builds
after recent ModuleSpec changes.

After the SlotIndex slot names were updated, it is possible to apply
stricter checks to live intervals.

Also treat bundles as bags of operands when checking live intervals.

thumb instruction.  The PC adjustment is +4 in Thumb mode and +8 in ARM mode.

The MIOperands iterator can visit operands on a single instruction, or
all operands in a bundle.  This simplifies code like the register
allocator that treats bundles as a set of operands.

Introduce __asan_set_error_report_callback() to allow the client program post-process the error reports.
If the callback is set, Report() and Printf() print the reports into a buffer (together with stderr), which is then passed to the client.

Enhance the logic that detects new value numbers to take this into account,
for a tiny compile time speedup.  Fix a comment typo while there.

%cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and
with "false" under the false edge.  This change enhances this to replace the
negated compare (A!=B) with "false" under the true edge and "true" under the
false edge.  Reported to improve perlbench results by 1%.

If the assignment operator is a scalar type, we continue to incorrectly reject
the initializer, but semantic analysis (and codegen) is correct for overloaded
operators.

There's more potential here, but these Exprs aren't used that often so I don't feel like doing heroic bit packing right now.
