* allchblk.c (GC_allochblk, GC_allochblk_nth): Use
OBJ_SZ_TO_BLOCKS_CHECKED instead of OBJ_SZ_TO_BLOCKS.
* malloc.c (GC_alloc_large): Likewise.
* alloc.c (GC_expand_hp_inner): Type of "bytes" local variable changed
from word to size_t; cast ROUNDUP_PAGESIZE argument to size_t; prevent
overflow when computing GC_heapsize+bytes > GC_max_heapsize.

value.

* headers.c (GC_scratch_alloc): Change type of bytes_to_get from word
to size_t (because ROUNDUP_PAGESIZE_IF_MMAP result type changed).
* include/private/gc_priv.h: Include limits.h (unless SIZE_MAX already
defined).
* include/private/gc_priv.h (GC_SIZE_MAX, GC_SQRT_SIZE_MAX): Move from
malloc.c file.
* include/private/gc_priv.h (SIZET_SAT_ADD): New macro (defined before
include gcconfig.h).

if no value wrap around is guaranteed.

(because ROUNDED_UP_GRANULES and GRANULES_TO_BYTES guarantees no value
wrap around).

Expand ROUNDUP_PAGESIZE macro but without value wrap-around checking
(the argument is of word type).

~GC_page_size+1 (because GC_page_size is unsigned); remove redundant
cast to size_t.

to SBRK_ARG_T.

to size_t.
