* tree-flow-inline.h (get_subvar_at): Use binary search.
(get_first_overlapping_subvar): New function to binary search
for the first overlapping subvar.
* tree-ssa-operands.c (add_vars_for_offset): Strip down to
just handle adding subvars for a pointed-to subvar. Optimize
and use get_first_overlapping_subvar.
(add_vars_for_bitmap): Fold into single caller.
(add_virtual_operand): Streamline, inherit add_vars_for_bitmap
and non pointed-to bits of add_vars_for_offset.
