Douglas Gregor 8b2d2fe234 Allow reference binding of a reference of Objective-C object type to 
an lvalue of another, compatible Objective-C object type (e.g., a
subclass). Introduce a new initialization sequence step kind to
describe this binding, along with a new cast kind. Fixes PR7741.

John McCall 7cd1d97e33 Inline a special case of EmitAggregateCopy into EmitNullInitialization 
to avoid the awesome-but-wrong-in-this-case assertion in the canon EAC.
Fixes PR7834.

Also fix a subtle address-space bug in the memset path.

John McCall cf14216509 Store inheritance paths after CastExprs instead of inside them. 
This takes some trickery since CastExpr has subclasses (and indeed,
is abstract).

Also, smoosh the CastKind into the bitfield from Expr.

Drops two words of storage from Expr in the common case of expressions
which don't need inheritance paths.  Avoids a separate allocation and
another word of overhead in cases needing inheritance paths.  Also has
the advantage of not leaking memory, since destructors for AST nodes are
never run.

Dan Gohman 404c58847e Tidy up PMStack. Add a bunch of consts, use std::vector instead of 
std::deque, since this is a stack and only supports push/pop on
one end, and remove an unimplemented declaration.

Dale Johannesen a3bd31a923 Use sdmem and sse_load_f64 (etc.) for the vector 
form of CMPSD (etc.)  Matching a 128-bit memory

Chris Lattner 8139c98cf9 Correct -ftrapv to trap on errors, instead of calling the 
__overflow_handler entrypoint that David Chisnall made up.
Calling __overflow_handler is not part of the contract of
-ftrapv provided by GCC, and should never have been checked
in in the first place.

According to:
http://permalink.gmane.org/gmane.comp.compilers.clang.devel/8699

David is using this for some of arbitrary precision integer stuff
or something, which is not an appropriate thing to implement on
this.

Jakob Stoklund Olesen 45e07c8fc5 Lazily defer duplicating the live interval we are splitting until we know it is 
necessary.

Sometimes, live range splitting doesn't shrink the current interval, but simply
changes some instructions to use a new interval. That makes the original more
suitable for spilling. In this case, we don't need to duplicate the original.

Jakob Stoklund Olesen 0e7752407c Don't try to verify LiveIntervals for physical registers. 
When a physical register is in use, some alias of that register has a live
interval with a relevant live range. That is the sad state of intervals after
physreg coalescing of subregs, and it is good enough for correct register
allocation.
