John McCall a2342eb857 Fix a bug in the emission of __real/__imag l-values on scalar operands. 
Fix a bug in the emission of complex compound assignment l-values.
Introduce a method to emit an expression whose value isn't relevant.
Make that method evaluate its operand as an l-value if it is one.
Fixes our volatile compliance in C++.

John McCall 8d75243029 Expression statements undergo lvalue-to-rvalue conversion in C, 
but not in C++, so don't emit aggregate loads of volatile references
in null context in C++.  Happens to have been caught by an assertion.
We do not get the scalar case right.  Volatiles are really broken.
