This patch removes the unused ebitmap, and then removes some sbitmap functions only used by ebitmap.

This patch removes the unused ebitmap, and then removes some sbitmap functions
only used by ebitmap.  The functions removed are:

SET_BIT_WITH_POPCOUNT
RESET_BIT_WITH_POPCOUNT
bitmap_copy_n
bitmap_range_empty_p
sbitmap_popcount

In addition, two functions have been made private to the implementation file:

SBITMAP_SIZE_BYTES
sbitmap_verify_popcount

Tested on x86-64.
