Fix the representation of wide strings in the AST and IR so that it uses the native representation of integers for the elements.  This fixes a bunch of nastiness involving
treating wide strings as a series of bytes.

In x86_64, when calling an Objective-C method that returns a _Complex long double, make sure to use the objc_msgSend_fp2ret function which ensures that the return value will be {0, 0} if the receiver is nil.

In case of template specialization, do not try to delay emitting debug info for concrete type in -flimit-debug-info mode. This fixes some of the failures from bs15503.exp tests in gdb testsuite.

expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.

Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

statements. As noted in the documentation for the AST node, the
semantics of __if_exists/__if_not_exists are somewhat different from
the way Visual C++ implements them, because our parsed-template
representation can't accommodate VC++ semantics without serious
contortions. Hopefully this implementation is "good enough".
