Fix LOOKS_LIKE_PTR for 64-bit platforms
I'm not sure what this is used for. But it won't correctly
detect RTS-filled slop on 64-bit platforms.
Test Plan:
Untested. But I did verify that
unsigned long x = (unsigned long)0xaaaaaaaaaaaaaaaaULL;
compiles warning-free and produces the expected output using both
gcc and clang, with -Wall -Wextra -O, and with and without -m32.
