Summary:
Ok, here is somewhat addition to D6217 aiming to preserve old darwin behavior wrt the typedefed types. The actual change to SemaChecking turned out to be pretty gross, in particular:
1. We need to extract the typedef'ed type for proper diagnostics
2. We need to walk over paren expressions as well

Summary:
Consider the following nifty 1 liner: (0 ? csqrtl(2.0f) : sqrtl(2.0f)). One can easily obtain such code from e.g. tgmath. Right now it produces an assertion because we fail to do the promotion real => _Complex real.
The case was properly handled previously (old handleOtherComplexFloatConversion routine), but was forgotten in the current version. This seems to be about fallout from r219557

but whose operand isn't a float: specifically, __real__ and __imag__. Instead
of filtering these out, just implement them.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

LHS type and the computation result type; this encodes information into
the AST which is otherwise non-obvious. Fix Sema to always come up with the
right answer for both of these types. Fix IRGen and the analyzer to
account for these changes. This fixes PR2601. The approach is inspired
by PR2601 comment 2.
Note that this changes real *= complex in CodeGen from a silent
miscompilation to an explicit error.
I'm not really sure that the analyzer changes are correct, or how to
test them... someone more familiar with the analyzer should check those
changes.
