Subject: Fix various intptr_t issues by defining its width in `getIntTypeInfo`
 (#6786)

* Define a bit size for the intptr types

* Fix intptr_t sign

* Extend intptr test to check for previously broken operations

* Fix intptr vector test on CUDA

* Handle intptr size in getAnyValueSize

* Fix formatting

* Try with __ARM_ARCH_ISA_64

* On macs, int64_t != intptr_t

Yikes

* Move define to prelude header

* Also check apple in host-prelude

* Fix define location
