This is consistent/interoperable with GCC 4.7 (& __cxa_deleted_function isn't
present in 4.4 - not sure when it got added, but you'll need something with
that function available for this to work).

AAPCS ABI Section 7.1.4 [1] specifies that va_list
should be defined as struct __va_list { void *__ap;};
And in C++, it is defined in namespace std.

 - outside C++, return undef (behavior is not undefined unless the value is used)
 - in C++, with -fcatch-undefined-behavior, perform an appropriate trap
 - in C++, produce an 'unreachable' (behavior is undefined immediately)

Currently, it's ignored if the number of set bits isn't divisible by 4.

Allowing individual targets to determine whether a given calling convention is allowed or ignored with warning. This allows for correct name mangling for x64 targets on Windows, which in turn allows for linking against the Win32 APIs.

Fixes PR13782

CodeGen: Copy tail padding when we're not dealing with a trivial copy assign or move assign operator.

This fixes a regression from r162254, the optimizer has problems reasoning
about the smaller memcpy as it's often not safe to widen a store but making it
smaller is.

observe their addresses (taking their address gives the vtable slot) so we are
free to merge their definitions.

typeid (and a couple other non-standard places where we can transform an
unevaluated expression into an evaluated expression) is special
because it introduces an an expression evaluation context,
which conflicts with the mechanism to compute the current
lambda mangling context.  PR12123.

I would appreciate if someone would double-check that we get the mangling
correct with this patch.

enough information so we can mangle them correctly in cases involving
dependent parameter types. (This specifically impacts cases involving
null pointers and cases involving parameters of reference type.)
Fix the mangler to use this information instead of trying to scavenge
it out of the parameter declaration.

be sure to delete the complete object pointer, not the original
pointer.  This is necessary if the base being deleted is at a
non-zero offset in the complete object.  This is only required
for objects with virtual destructors because deleting an object
via a base-class subobject when the base does not have a virtual
destructor is undefined behavior.

Noticed while reviewing the last four years of cxx-abi-dev
activity.

into the enclosing scope;  this is a more accurate model but is
(I believe) unnecessary in my test case due to other flaws.
However, one of those flaws is now intentional:  blocks which
appear in return statements can be trivially observed to not
extend in lifetime past the return, and so we can allow a jump
past them.  Do the necessary magic in IR-generation to make
this work.
