Fix placement of forced local symbols in the dynamic symbol table.
Gold was not placing forced-local symbols (e.g., hidden visibility)
at the front of the dynamic symbol table, or including them in the
count of local symbols recorded in the .dynsym section's sh_info field.
gold/
* layout.cc (Layout::finalize): Track count of forced-local symbols
in .dynsym.
(Layout::create_symtab_sections): Add local_dynamic_count parameter;
use that instead of sh_info value.
(Layout::create_dynamic_symtab): Add pforced_local_dynamic_count
parameter; pass it to Symtab::set_dynsym_indexes(). Include forced
locals in sh_info value. Pass index of first real global to
Dynobj::create_gnu_hash_table() and Dynobj::create_elf_hash_table().
* layout.h (Layout::create_symtab_sections): Add local_dynamic_count
parameter.
(Layout::create_dynamic_symtab): Add pforced_local_dynamic_count
parameter.
* symtab.cc (Symbol_table::set_dynsym_indexes): Add pforced_local_count
parameter. Process forced-local symbols first and return the count.
(Symbol_table::finalize): Update comments.
* symtab.h (Symbol_table::set_dynsym_indexes): Add pforced_local_count
parameter.
(Symbol_table::first_dynamic_global_index_): Update comment.
(Symbol_table::dynamic_count_): Update comment.
* testsuite/Makefile.am (ifuncmod1.sh): New test case.
* testsuite/Makefile.in: Regenerate.
* testsuite/ifuncmod1.sh: New shell script.
