sbitmap: Add bitmap_all_bits_in_range_p function

This patch adds the `bitmap_all_bits_in_range_p` function in sbitmap,
which checks if all the bits in a range are set.

Helper function `bitmap_bit_in_range_p` has also been added, in order
to be used by `bitmap_all_bits_in_range_p` and
`bitmap_any_bit_in_range_p`.  When the function's `any_inverted`
parameter is true, the function checks if any of the bits in the range
is unset, otherwise it checks if any of them is set.

Function `bitmap_any_bit_in_range_p` has been updated to call
`bitmap_bit_in_range_p` with the `any_inverted` parameter set to
false, retaining its previous functionality.

Function `bitmap_all_bits_in_range_p` calls `bitmap_bit_in_range_p`
with `any_inverted` set to true and returns the negation of the
result, i.e. true if all the bits in the range are set.

gcc/ChangeLog:

	* sbitmap.cc (bitmap_any_bit_in_range_p):
	Call and return the result of `bitmap_bit_in_range_p` with the
	`any_inverted` parameter set to false.
	(bitmap_bit_in_range_p): New function.
	(bitmap_all_bits_in_range_p): New function.
	* sbitmap.h (bitmap_all_bits_in_range_p): New function.
