Replace check_mul_overflow_size_t with __builtin_mul_overflow
Checked on x86_64-linux-gnu and i686-linux-gnu.
* malloc/alloc_buffer_alloc_array.c (__libc_alloc_buffer_alloc_array):
Use __builtin_mul_overflow in place of check_mul_overflow_size_t.
* malloc/dynarray_emplace_enlarge.c (__libc_dynarray_emplace_enlarge):
Likewise.
* malloc/dynarray_resize.c (__libc_dynarray_resize): Likewise.
* malloc/reallocarray.c (__libc_reallocarray): Likewise.
* malloc/malloc-internal.h (check_mul_overflow_size_t): Remove
function.
* support/blob_repeat.c (check_mul_overflow_size_t,
(minimum_stride_size, support_blob_repeat_allocate): Likewise.
