Change various hash tables from htab_t to hash_table.
Each file is independent.

attribs.c scoped_attributes::attribute_hash
bitmap.c bitmap_desc_hash
dwarf2cfi.c trace_index
dwarf2out.c break_out_includes::cu_hash_table
dwarf2out.c copy_decls_for_unworthy_types::decl_table
dwarf2out.c optimize_external_refs::map
dwarf2out.c output_comp_unit::extern_map
dwarf2out.c output_comdat_type_unit::extern_map
dwarf2out.c output_macinfo::macinfo_htab
dwarf2out.c optimize_location_lists::htab
dwarf2out.c dwarf2out_finish::comdat_type_table
except.c ehspec_hash_type
except.c assign_filter_values::ttypes
except.c assign_filter_values::ehspec
except.c sjlj_assign_call_site_values::ar_hash
except.c convert_to_eh_region_ranges::ar_hash
trans-mem.c tm_new_mem_hash
tree-browser.c TB_up_ht
tree-eh.c finally_tree

Move the declaration of hash_table <alloc_pool_hasher> alloc_pool_hash
in alloc-pool.c to after the method definitions for its parameter
class.


Tested on x86-64.

Okay for branch?


Index: gcc/ChangeLog

2012-11-30  Lawrence Crowl  <crowl@google.com>

	* alloc-pool.c (static hash_table <alloc_pool_hasher> alloc_pool_hash):
	Move declaration to after the type's method definitons.

	* attribs.c (htab_t scoped_attributes::attribute_hash):

	(assign_filter_values::ttypes): Likewise.
	(assign_filter_values::ehspec): Likewise.
	(sjlj_assign_call_site_values::ar_hash): Likewise.
	(convert_to_eh_region_ranges::ar_hash): Likewise.

	* trans-mem.c (htab_t tm_new_mem_hash):
	Change type to hash_table.  Update dependent calls and types.

	* tree-browser.c (htab_t TB_up_ht):
	Change type to hash_table.  Update dependent calls and types.
