JDK-8177481 - Prepare Runtime code for -Wconversion
Description
JVMTI code in jvmtiClassFileReconstitutor and jvmtiRedefineClasses narrows ints into u2's to match fields in the constant pool.

These get -Wconversion warnings when implicitly narrowed.

When compiling with -Wconversion without -Werror, this was the count of occurrences in these files.
