c++: fix constexpr cast from void* diag issue [PR116741]
The result of build_fold_indirect_ref can be a COMPONENT_REF in
which case using DECL_SOURCE_LOCATION will crash. Look at its op1
instead.
PR c++/116741
gcc/cp/ChangeLog:
* constexpr.cc (cxx_eval_constant_expression) <case CONVERT_EXPR>: If
the result of build_fold_indirect_ref is a COMPONENT_REF, use its op1.
Check DECL_P before calling inform.
gcc/testsuite/ChangeLog:
* g++.dg/cpp26/constexpr-voidptr4.C: New test.
