support it.  I don't know what evaluation method we use for complex
arithmetic, so I don't know whether/if we should warn about use of
CX_LIMITED_RANGE.

This concludes my planned hacking on STDC pragmas, flame away :)

for a token is set, this makes the diagnostic "expanded from stack" work
for this diagnostic.  Add a testcase for PR3918.

Another piece of the conditional operator puzzle. We'll want to use FindCompositePointerType in some other places, too.

in a function-like macro body.  This has the added bonus of moving some
function-like macro specific code out of the object-like macro codepath.

@class but no implementation.  This was broken in all 3 runtime
impls.

 - The confusing IRgen bitfield interface is partly to blame here;
   fixing the functional error for now, cleanups to the interface to
   follow.

the scope checker to not think @catches are nested in each other, eliminating
some bogus notes.

reasonably well except for the problem that @catches are nested within
each other in the AST, giving the ugly diagnostics in L8.

statements don't end up in the LabelMap so we don't have a quick way
to filter them.  We could add state to Sema (a "has vla" and "has 
jump" bit) to try to filter this out, but that would be sort of gross
and I'm not convinced it is the best way.  Thoughts welcome.
