ld: Set non_ir_ref_regular on source for assignment
We need to set non_ir_ref_regular on the source for assignment to get
the correct LTO resolution:
190 a27be7f4ad90c5ce PREVAILING_DEF real_g
instead of
190 30c3b2d8f967f5ea PREVAILING_DEF_IRONLY real_g
PR ld/26163
* ldexp.c (exp_fold_tree_1): Set non_ir_ref_regular on the source
for assignment.
* testsuite/ld-plugin/lto.exp: Run ld/26163 test.
* testsuite/ld-plugin/pr26163a.c: New file.
* testsuite/ld-plugin/pr26163b.c: Likewise.
