Now that parsing, semantic analysis, and (I think) code generation of
pseudo-destructor expressions and explicit destructor calls works,
update the example-dynarray.cpp test to destroy the objects it
allocates and update the test to actually compile + link.
The code seems correct, but the Clang-compiled version dies with a
malloc error. Time to debug!

involve qualified names, e.g., x->Base::f. We now maintain enough
information in the AST to compare the results of the name lookup of
"Base" in the scope of the postfix-expression (determined at template
definition time) and in the type of the object expression.

member pointer types.
Introduce test cases for member pointer comparisons, including those
that involve the builtin operator candidates implemented earlier.

template argument deduction from a conversion function (C++

Implement support for C++ Substitution Failure Is Not An Error
(SFINAE), which says that errors that occur during template argument
deduction do *not* produce diagnostics and do not necessarily make a
program ill-formed. Instead, template argument deduction silently
fails. This is currently implemented for template argument deduction
during matching of class template partial specializations, although
the mechanism will also apply to template argument deduction for
function templates. The scheme is simple:
- If we are in a template argument deduction context, any diagnostic
that is considered a SFINAE error (or warning) will be
suppressed. The error will be propagated up the call stack via the
normal means.
- By default, all warnings and errors are SFINAE errors. Add the
NoSFINAE class to a diagnostic in the .td file to make it a hard
error (e.g., for access-control violations).
Note that, to make this fully work, every place in Sema that emits an
error *and then immediately recovers* will need to check
Sema::isSFINAEContext() to determine whether it must immediately
return an error rather than recovering.

specialization's arguments are identical to the implicit template
arguments of the primary template. Typically, this is meant to be a
declaration/definition of the primary template, so we give that
advice.

and core issues 275 and 259 will both affect the checking that we do
for explicit instantiations (but are not yet implemented).

This also cleans up the propagation of template information through
declaration parsing, which is used to improve some diagnostics.
