This patch is the main part of a consolodation of the hash_table
patches to the cxx-conversion branch for files not under gcc/config.

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

* tree-parloops.c'reduction
* tree-parloops.c'name_to_copy

Fold reduction_info_hash and reduction_info_eq into new struct
reduction_hasher.  Fold name_to_copy_elt_eq and name_to_copy_elt_hash
into new struct name_to_copy_hasher.

* trans-mem.c'tm_log

Fold tm_log_hash, tm_log_eq, tm_log_free into new struct log_entry_hasher.

* trans-mem.c'tm_memopt_value_numbers

Fold tm_memop_hash, tm_memop_eq into new struct tm_memop_hasher.

* tree-ssa-strlen.c'decl_to_stridxlist_htab

Fold decl_to_stridxlist_hash into new struct stridxlist_hasher.

* tree-ssa-loop-ivopts.c'ivopts_data::inv_expr_tab

Fold htab_inv_expr_hash and htab_inv_expr_eq into new struct
iv_inv_expr_hasher.

* tree-ssa-uncprop.c'equiv

Equiv renamed to val_ssa_equiv because of name ambiguity with local variables.

Fold equiv_hash, equiv_eq and equiv_free into new struct val_ssa_equiv_hasher.

Renamed variables equiv_hash_elt to an_equiv_elt because of name ambiguity
with struct type.  Changed equiv_hash_elt_p to an_equiv_elt_p to match.

* tree-ssa-phiopt.c'seen_ssa_names

Fold name_to_bb_hash and name_to_bb_eq into new struct ssa_names_hasher.

* tree-ssa-structalias.c'pointer_equiv_class_table
* tree-ssa-structalias.c'location_equiv_class_table

Fold equiv_class_label_hash and equiv_class_label_eq into new
struct equiv_class_hasher.

* tree-ssa-structalias.c'shared_bitmap_table

Fold shared_bitmap_hash and shared_bitmap_eq into new struct
shared_bitmap_hasher.

* tree-ssa-live.c'var_map_base_init::tree_to_index

New struct tree_int_map_hasher.

* tree-sra.c'candidates

Fold uid_decl_map_hash and uid_decl_map_eq into new struct
uid_decl_hasher.  This change moves the definitions from tree-ssa.c
into tree-sra.c and removes the declarations from tree-flow.h

tree-browser.c

Remove stale declaration of removed TB_parent_eq.
Fix template parameter for base class to match value_type.

gimple.h

Use gimplify_hasher::hash rather than gimple_tree_hash in the
  assertion check.
Change return values to match return type. (I.e. no conversions.)

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.

* ggc-common.c'loc_hash
* ggc-common.c'ptr_hash

Add a new hash_table method elements_with_deleted to meet the needs of
gcc-common.c.

Correct many methods with parameter types compare_type to the correct
value_type.  (Correct code was unlikely to notice the change, but
incorrect code will.)

* tree-complex.c'complex_variable_components
* tree-parloops.c'eliminate_local_variables_stmt::decl_address
* tree-parloops.c'separate_decls_in_region::decl_copies

Move hash table declarations to a new tree-hasher.h, to resolve
compilation dependences and because they are used in few places.

* lto-streamer.h'output_block::string_hash_table
* lto-streamer-in.c'file_name_hash_table
* lto-streamer.c'tree_htab

The struct string_slot moves from data-streamer.h to lto-streamer.h to
resolve compilation dependences.

Tested on x86_64.

Diego Novillo 9771b26396 This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'.
This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'.  The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.

I have tested the patch pretty extensively:

- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).

We no longer access the vectors via VEC_* macros.  The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".

The only thing I could not do is create proper ctors and dtors for the
vec class.  Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).

This means that creation and destruction must be explicit.  There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.

For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'.  See the wiki
page for details.

The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).

When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)).  Otherwise, it will
emit an error.

Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.

Lawrence Crowl d7c028c07b This patch normalizes more bitmap function names.
sbitmap.h

    TEST_BIT -> bitmap_bit_p
    SET_BIT -> bitmap_set_bit
    SET_BIT_WITH_POPCOUNT -> bitmap_set_bit_with_popcount
    RESET_BIT -> bitmap_clear_bit
    RESET_BIT_WITH_POPCOUNT -> bitmap_clear_bit_with_popcount

  basic-block.h

    sbitmap_intersection_of_succs -> bitmap_intersection_of_succs
    sbitmap_intersection_of_preds -> bitmap_intersection_of_preds
    sbitmap_union_of_succs -> bitmap_union_of_succs
    sbitmap_union_of_preds -> bitmap_union_of_preds

The sbitmap.h functions also needed their numeric paramter changed
from unsigned int to int to match the bitmap functions.

Callers updated to match.

Tested on x86-64, config-list.mk testing.

Lawrence Crowl f61e445a74 This patch implements the unification of the *bitmap interfaces as discussed.
Essentially, we rename ebitmap and sbitmap functions to use the same names
as the bitmap functions.  This rename works because we can now overload
on the bitmap type.  Some macros now become inline functions to enable
that overloading.

The sbitmap non-bool returning bitwise operations have been merged with
the bool versions.  Sometimes this merge involved modifying the non-bool
version to compute the bool value, and sometimes modifying bool version to
add additional work from the non-bool version.  The redundant routines have
been removed.

The allocation functions have not been renamed, because we often do not
have an argument on which to overload.  The cardinality functions have not
been renamed, because they have different parameters, and are thus not
interchangable.  The iteration functions have not been renamed, because
they are functionally different.

Tested on x86_64, contrib/config-list.mk testing passed.
