Use intptr_t when storing an integer in a pointer 

Cast the integer type to (u)intptr_t before casting to "void *".  In
CHERI C/C++ we warn on bare casts from integers to pointers to catch
attempts to create pointers our of thin air.  We allow the warning to be
supressed with a suitable cast through (u)intptr_t.
