tree-optimization/102943 - use tree form for sbr_sparse_bitmap
The following arranges to remove an indirection do the bitvector
in sbr_sparse_bitmap by embedding bitmap_head instead of bitmap
and using the tree form (since we only ever set/query individual
aligned bit chunks). That shaves off 6 seconds from 70 seconds
of the slowest 521.wrf_r LRANS unit build.

PR tree-optimization/102943
* gimple-range-cache.cc (sbr_sparse_bitmap::bitvec):
Make a bitmap_head.
(sbr_sparse_bitmap::sbr_sparse_bitmap): Adjust and switch
to tree view.
(sbr_sparse_bitmap::set_bb_range): Adjust.
(sbr_sparse_bitmap::get_bb_range): Likewise.
