Subject: Add an intptr type to runtime; needed in FreeBSD

Add an intptr type to runtime; needed in FreeBSD

In thread.c, we need to cast to whatever the native
size of intptr is on the system, but we only have
uintptr available. They're the same size, but can't
do signed casts without this one :).
