LGTM!
FWIW, here's a test file that does not trip the sanitizer before this PR and
_does_ trip after the PR:
```c
#include
int main(int argc, char **argv) {
void *p = NULL;
printf("p: %p\n", p);
p = p - argc;
printf("p: %p\n"

Changes
Pointer arithmetic on void pointers (a GNU extension) was going through a
different code path and bypassed the pointer-overflow sanitizer.
Fixes https://github.com/llvm/llvm-project/issues/66451.
