A patch I have developed for PR 50012 issues a warning for some code in
ipa-cp.c in which a variable of type int is compared to the return value
of VEC_length, which is unsigned int. This should logically require a
type cast, and actually I'm not sure why the warning is not issued
without my patch. In any case, this patch adds the required type
casts. Committed as obvious.

comparing param_index to VEC_length result.
