John McCall 824fd1dcff Introduce an r-value to l-value cast kind. I'm not promising anything
about the reliability of this yet.

John McCall 07bb19667a Simplify some complex emission and implement correct semantics for
assignment to volatiles in C.  This in effect reverts some of mjs's
work in and around r72572.  Basically, the C++ standard is quite
clear, except that it lies about volatile behavior approximating
C's, whereas the C standard is almost actively misleading.

John McCall d764625448 Add a few more complex-related cast kinds that arise due to arbitrary
implicit conversions;  the last batch was specific to promotions.
I think this is the full set we need.  I do think dividing the cast
kinds into floating and integral is probably a good idea.

Annotate a *lot* more C casts with useful cast kinds.

David Chisnall dd84ef1e62 Add a -ftrapv-handler= option which allows a handler to invoke instead of simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit.

John McCall 7a626f63f7 one piece of code is responsible for the lifetime of every aggregate
slot.  The easiest way to do that was to bundle up the information
we care about for aggregate slots into a new structure which demands
that its creators at least consider the question.

I could probably be convinced that the ObjC 'needs GC' bit should
be rolled into this structure.
Implement generalized copy elision.  The main obstacle here is that
IR-generation must be much more careful about making sure that exactly

Daniel Dunbar 2f8df98c92 IRgen: Fix silly thinko in r112021, which was generating code for the same expr

John McCall 7a9aac2d9f Abstract out everything having to do with member pointers into the ABI
class;  they should just be completely opaque throughout IR gen now,
although I haven't really audited that.

Fix a bug apparently inherited from gcc-4.2 where we failed to null-check
member data pointers when performing derived-to-base or base-to-derived
conversions on them.

John McCall a1dee5300b Experiment with using first-class aggregates to represent member function
pointers.  I find the resulting code to be substantially cleaner, and it
makes it very easy to use the same APIs for data member pointers (which I have
conscientiously avoided here), and it avoids a plethora of potential
inefficiencies due to excessive memory copying, but we'll have to see if it
actually works.

John McCall 131d97d809 Extract member function pointer comparison and null comparison into
the ABI code.  Implement correct semantics for these on ARM.

I believe this completes the implementation of member function pointers
on ARM.

I think I'm going to switch member function pointers over to be
non-aggregates while I have all this in mind.
