Prevent ArtMethod clearing race
There was race condition where the GC would be visiting the methods
of a class while the class linker overwrote the contents with 0xFE
when copying to a new array.
Since the GC is holding the class table lock at this time, we can
use this lock in the class linker to prevent the race.
