This patch is a consolodation of the hash_table patches to the
cxx-conversion branch for files under gcc/config.

Update various hash tables from htab_t to hash_table.
Modify types and calls to match.

* config/arm/arm.c'arm_libcall_uses_aapcs_base::libcall_htab

Fold libcall_eq and libcall_hash into new struct libcall_hasher.

* config/ia64/ia64.c'bundle_state_table

Fold bundle_state_hash and bundle_state_eq_p into new struct
bundle_state_hasher.

* config/mips/mips.c'mips_offset_table

Fold mips_lo_sum_offset_hash and mips_lo_sum_offset_eq into new
struct mips_lo_sum_offset_hasher.

In mips_reorg_process_insns, change call to for_each_rtx to pass
a pointer to the hash_table rather than a htab_t.  This change
requires then dereferencing that pointer in mips_record_lo_sum to
obtain the hash_table.

* config/sol2.c'solaris_comdat_htab

Fold comdat_hash and comdat_eq into new struct comdat_entry_hasher.

* config/i386/winnt.c'i386_pe_section_type_flags::htab

* config/i386/winnt.c'i386_find_on_wrapper_list::wrappers

Fold wrapper_strcmp into new struct wrapped_symbol_hasher.

Tested on x86_64.  Tested with config-list.mk.

This patch re-enables -fdump-passes.

This patch re-enables -fdump-passes. It had stopped working because
dump_passes was changed to use the FOR_EACH_DEFINED_FUNCTION iterator,
however, functions are not marked as defined until after dump_passes
is called, in cgraph_analyze_functions. Fixed by iterating over all
functions.

2013-05-29  Teresa Johnson  <tejohnson@google.com>

* passes.c (dump_passes): Use FOR_EACH_FUNCTION since
functions are not yet marked as defined.
