A recent change in ipa-inline-analysis.c introduced a comparison
between signed and unsigned values, which broke bootstrap due to
-Wsign-compare (PR50005). Fixed by casting VEC_length to int before
using it in a comparison, as is done in many other places.
Tested on i686-linux and sparc64-linux. Pre-approved by Jan Hubicka
in the PR trail.
Ok for trunk? (I don't have svn write access.)
(The warning is only visible with the C FE due to an unrelated C++ FE
diagnostics bug, which I've filed as PR50012.)

* ipa-inline-analysis (remap_predicate): Add cast to
silence signed/unsigned comparison warning.
