Fix calloc_explicitly_typed in case of lb*n overflow
(Cherry-pick commit 41a9ed4 from 'release-7_4' branch.)

* typd_mlc.c: Include limits.h (for SIZE_MAX).
* typd_mlc.c (GC_SIZE_MAX, GC_SQRT_SIZE_MAX): New macro (same as in
malloc.c).
* typd_mlc.c (GC_calloc_explicitly_typed): Return NULL if lb * n
overflows (same algorithm as in calloc defined in malloc.c); eliminate
lb *= n code duplication.
