Don't allow defining a block with a non-prototype type. Remove a

hack which introduces some strange inconsistencies in compatibility
for block pointers.
Note that unlike an earlier revision proposed on cfe-commits, this patch
still allows declaring block pointers without a prototype.

PR4287: allow a variadic prototype to make a subsequent K&R style
...
definition variadic. I'm not completely sure it's legal, but the
standard can be interpreted as making it legal, and gcc seems to think
it's legal, so I didn't add an extension warning.

Representation of and template instantiation for member
...
expressions. This change introduces another AST node,
CXXUnresolvedMemberExpr, that captures member references (x->m, x.m)
when the base of the expression (the "x") is type-dependent, and we
therefore cannot resolve the member reference yet.
Note that our parsing of member references for C++ is still quite
poor, e.g., we don't handle x->Base::m or x->operator int.

Avoid calling mergeTypes in C++. I think these are the correct C++
...
alternatives, but please correct me if I'm wrong.
I eventually plan to assert in mergeTypes that we aren't in C++ mode
because composite types are fundamentally not a part of C++. The
remaining callers for code in the regression tests are
Sema::WarnConflictingTypedMethods and CodeGenFunction::EmitFunctionProlog;
I'm not quite sure what the correct approach is for those callers.

Implement support for comparing pointers with <, >, <=, >=, ==, and !=
...
in C++, taking into account conversions to the "composite pointer
type" so that we can compare, e.g., a pointer to a derived class to a
pointer to a base class.
Also, upgrade the "comparing distinct pointer types" from a warning to
an error for C++, since this is clearly an error. Turns out that we
hadn't gone through and audited this code for C++, ever.
Fixes <rdar://problem/6816420>.
