6940520: CodeCache::scavenge_root_nmethods_do must fix oop relocations
Summary: ScavengeRootsInCode can lead to unfixed code-embedded oops.
Reviewed-by:

During testing of JSR 292's SPARC C2 port I found a couple of crashes
which came from unfixed code-embedded oops.

This can be triggered with ScavengeRootsInCode={1,2}.

The fix is to call fix_oop_relocations in
CodeCache::scavenge_root_nmethods_do after oops may have been updated.
