a5ccf8522b [clang][Interp] Not all RVO call expressions are initializing 
We do not necessarily prepare storage for the return value when
we are returning a complex value.

[clang][Interp] Handle complex values in visitBool() (#79452) 
In C++, we get a ComplexToBool cast, but we might not in C.

8c84096da1 [clang][Interp] Fix initializing _Complex values from DeclRefExpr 
See the comment I added. When initializing a complex value from a
DeclRefExpr, we need to manually copy both array elements.
This adds some unfortunate code duplication that I'm still pondering
on how to get rid of best.

casts as well as the old __real implementation.

88abd530ef [clang][Interp] Allow evaluating standalone complex expressions 
We reach visitExpr() when evaluating standalone expressions. However,
the RetValue() code path was unused before, because we never reach it,
even with structs or arrays.

RetValue expects a pointer on the stack it can take apart to return an
APValue, so provide it with one.
