d: Fix internal compiler error: in build_complex, at tree.c:2358
The conversion from the special _Complex enum to native complex used
build_complex, however the input value isn't necessarily a literal.
PR d/105004
gcc/d/ChangeLog:
* d-codegen.cc (build_struct_literal): Use complex_expr to build
complex expressions from __c_complex types.
gcc/testsuite/ChangeLog:
* gdc.dg/pr105004.d: New test.
