Fix bitmap registration of overheads.
2019-05-07 Martin Liska <mliska@suse.cz>
* bitmap.c (bitmap_register): Come up with
alloc_descriptor_max_uid and assign it for
a new bitmap.
(register_overhead): Use get_descriptor as
a descriptor.
(release_overhead): New.
(bitmap_elem_to_freelist): Call it.
(bitmap_elt_clear_from): Likewise.
(bitmap_obstack_free): Likewise.
(bitmap_move): Sensitively release memory.
* bitmap.h (struct GTY): Add alloc_descriptor and padding.
(bitmap_initialize): Initialize alloc_descriptor to zero.
* tree-ssa-pre.c (do_hoist_insertion): Use bitmap_move.
