Fix --defsym to copy symbol attributes.
Alan Modra committed a patch to Gnu ld to fix a problem encountered on PPC where the --defsym option wasn't copying the st_other bits to the newly-defined symbol. https://sourceware.org/ml/binutils/2014-07/msg00094.html Gold has the same problem, and additionally wasn't copying the symbol type. This patch fixes both problems, by copying the symbol type, visibility, and the remaining st_other bits to the new symbol for --defsym=sym1=sym2 assignments. gold/ * expression.cc (struct Expression::Expression_eval_info): Add new fields type_pointer, vis_pointer, and nonvis_pointer. (Expression::eval_maybe_dot): Add type_pointer, vis_pointer, and nonvis_pointer parameters. Adjust all calls. (Symbol_expression::value): Update type, visibility, and nonvis bits in caller. * script.cc (Symbol_assignment::sized_finalize): Update type, visibility, and remaining st_other bits for new symbol. * script.h: (Expression::eval_maybe_dot): Add type_pointer, vis_pointer, and nonvis_pointer parameters. * symtab.h (Symbol::set_type): New method. * testsuite/Makefile.am (defsym_test): New test. * testsuite/Makefile.in: Regenerate. * testsuite/defsym_test.c: New file. * testsuite/defsym_test.sh: New file.
