This patch switches most of the uses of intptr_t to uintptr_t within llvm-exegesis for the subprocess memory support. In the vast majority of cases we do not want a signed component of the address, hence making intptr_t undesirable. intptr_t is left for error handling, for example when making syscalls and we need to see if the syscall returned -1.
