expression kinds. This is (indirectly) a test verifying that the
recursive AST visitor is visiting the children of these expression
nodes.

pack expansions in template argument lists and function parameter
lists. The implementation of this paragraph should be complete
*except* for cases where we're substituting into one of the unexpanded
packs in a pack expansion; that's a general issue I haven't solved yet.
llvm-svn: 123188
allows an argument pack determines via explicit specification of
function template arguments to be extended by further, deduced
arguments. For example:
template<class ... Types> void f(Types ... values);
void g() {
f<int*, float*>(0, 0, 0); // Types is deduced to the sequence int*, float*, int
}
There are a number of FIXMEs in here that indicate places where we
need to implement + test retained expansions, plus a number of other
places in deduction where we need to correctly cope with the
explicitly-specified arguments when deducing an argument
pack. Furthermore, it appears that the RecursiveASTVisitor needs to be
auditied; it's missing some traversals (especially w.r.t. template
arguments) that cause it not to find unexpanded parameter packs when
it should.
The good news, however, is that the tr1::tuple implementation now
works fully, and the tr1::bind example (both from N2080) is actually
working now.

temporaries with no-return destructors. The CFG now properly supports
temporaries and implicit destructors which both makes this kludge no
longer work, and conveniently removes the need for it.
Turn on CFG handling of implicit destructors and initializers. Several
ad-hoc benchmarks don't indicate any measurable performance impact from
growing the CFG, and it fixes real correctness problems with warnings.
As a result of turning on these CFG elements, we started to tickle an
inf-loop in the unreachable code logic used for warnings. The fix is
trivial.

tuple class template. This implementation is boosted directly from the
variadic templates proposal. N2080.
Note that one section is #ifdef'd out. I'll implement that aspect of
template argument deduction next.

TreeTransform version of TransformExprs() rather than explicit loop,
so that we expand pack expansions properly. Test cast coming soon...

In particular, the iteration variable (if present) should be created and
destroyed in a narrow span around the loop body, and the body should
be emitted in a cleanup scope in case it's not a compound statement.
Otherwise, rename a few variables and use phis instead of temporary
variables for the index and buffer count.

parameters into parameter types, so that substitution of
explicitly-specified function template arguments uses the same
path. This enables the use of explicitly-specified function template
arguments with variadic templates.
llvm-svn: 122986
template whose last parameter is a parameter pack. This allows us to
form a call to, e.g.,
template<typename ...Args1, typename ...Args2>
void f(std::pair<Args1, Args2> ...pairs);
given zero or more instances of "pair".
