compiler: additional lvalue/rvalue context fixes
Fix lvalue/rvalue context mixup Set_and_use_temporary_expression's
do_get_backend() method. Enhance Mark_lvalue_varexprs to handle
conversions and temporary reference expressions, since occasionally
the front end emits code such as "deref(conv(tempref)) = ...".
