Log:
PR rtl-optimization/77919
* expr.c (expand_expr_real_1) <normal_inner_ref>: Only avoid forcing
into memory if both modes are complex and their inner modes have the
same precision. If the two modes are different complex modes, convert
each part separately and generate a new CONCAT.
* g++.dg/torture/pr77919-2.C: New test.
