Be more careful about picking a template parameter when we fail to substitute explicit template arguments into a function template

particular, don't complain about unused variables that have dependent
type until instantiation time, so that we can look at the type of the
variable. Moreover, only complain about unused variables that have
neither a user-declared constructor nor a non-trivial destructor.

unused, since the operation has side effects.

Add a SizeOfLargestEmptySubobject member to ASTRecordLayout. For C++ classes this will hold the largest empty subobject or 0 if the class doesn't have any empty subobjects.

for, and switch), be careful to construct the full expressions as soon
as we perform template instantation, so we don't either forget to call
temporary destructors or destroy temporaries at the wrong time. This
is the template-instantiation analogue to r103187, during which I
hadn't realized that the issue would affect the handling of these
constructs differently inside and outside of templates.

Fixes a regression in Boost.Function.

when it detects undefined behavior.  llvm.trap generally codegens into some
thing really small (e.g. a 2 byte ud2 instruction on x86) and debugging this
sort of thing is "nontrivial".  For example, we now compile:

void foo() { *(int*)0 = 42; }

into:

_foo:
	pushl	%ebp
	movl	%esp, %ebp
	ud2

Some may even claim that this is a security hole, though that seems dubious
to me.  This addresses rdar://7958343 - Optimizing away null dereference 
potentially allows arbitrary code execution

with a vector input and output into a shuffle vector.  This sort of 
sequence happens when the input code stores with one type and reloads
with another type and then SROA promotes to i96 integers, which make
everyone sad.
