JDK-8198918 - jio_snprintf and friends are not checked by -Wformat
Description
JVMCIGlobals::check_jvmci_flags_are_consistent uses jio_fprintf to print a warning message including the value of TieredStopAtLevel. The type of that option is intx, but "%d" is used to print it, which is incorrect for 64bit platforms.

This begs the question of why TieredStopAtLevel is of type intx rather than int, since it's value is restricted to the range [0-4]. For that matter, there are a lot of other options in compiler_globals.hpp that that seem to be inappropriately typed as intx.
