Ensure when NotifyMethodRedefined is called the ArtMethod is valid

Previously we were calling Jit::JitCodeCache::NotifyMethodRedefined
with an ArtMethod that was not fully valid. This could cause OOB
memory accesses if NotifyMethodRedefined attempts to access the
incorrect dex-file associated with the method at that time. This
occurs if the method is a native method. By looking at the wrong dex
file the JIT will get an incorrect MethodID and Shorty meaning it is
unable to correctly update the jit-code-cache.

Test: ./test.py --host -j50
Test: Run WIP dexmaker tests that hit this issue.
