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.

  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.

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.
