Now that vrange_storage is in its own file, I think it's prudent to
move all the vrange allocator code there since it's all related.
The users of value-range.h do not need to know the implementation
details of the storage facilities.
Tested and benchmarked on x86-64 Linux.
gcc/ChangeLog:
* gimple-range-cache.cc: Include value-range-storage.h.
* gimple-range-cache.h (class block_range_cache): Add "class" to
m_range_allocator.
* gimple-range-edge.cc
(gimple_outgoing_range::gimple_outgoing_range): Allocate allocator.
(gimple_outgoing_range::~gimple_outgoing_range): Free allocator.
(gimple_outgoing_range::calc_switch_ranges): Dereference allocator.
* gimple-range-edge.h: Add "class" to m_range_allocator.
* gimple-range-infer.cc
(infer_range_manager::infer_range_manager): Allocate allocator.
(infer_range_manager::~infer_range_manager): Free allocator.
(infer_range_manager::get_nonzero): Dereference allocator.
(infer_range_manager::add_range): Same.
* gimple-range-infer.h (class vrange_allocator): Add "class" to
m_range_allocator.
* value-range-storage.h (class vrange_allocator): Move from
value-range.h.
(class obstack_vrange_allocator): Same.

Finally, the meat of the work. Convert ranger and associated clients
to vrange.
Everything's relatively mechanical given the previous patches. I did
include a minor cleanup in the edge code. There's no need to check
that the type of the switch is an integer as non-integer switches are
invalid. I verified this with an appropriately coded assert.
Tested on x86-64 & ppc64le Linux.

This patch revamps the range allocator to handle generic vrange's.
I've cleaned it up somehow to make it obvious the various things you
can allocate with it. I've also moved away from overloads into
distinct names when appropriate.
The various entry points are now:
// Allocate a range of TYPE.
vrange *alloc_vrange (tree type);
// Allocate a memory block of BYTES.
void *alloc (unsigned bytes);
// Return a clone of SRC.
template <typename T> T *clone (const T &src);
It is now possible to allocate a clone of an irange, or any future
range types:
irange *i = allocator.clone <irange> (some_irange);
frange *f = allocator.clone <frange> (some_frange);
You can actually do so without the <>, but I find it clearer to
specify the vrange type.
So with it you can allocate a specific range type, or vrange, or a
block of memory.
I have rewritten the C style casts to C++ casts, since casts tend to
be hints of problematic designs. With the C++ casts you can at least
grep for them easier. Speak of which, the next patch, which converts
ranger to vrange, will further clean this space by removing some
unnecessary casts.
Tested on x86-64 Linux and ppc64le Linux.
