7003554: (tiered) assert(is_null_object() || handle() != NULL) failed: cannot embed null pointer
...

6985015: C1 needs to support compressed oops
...
This change implements compressed oops for C1 for x64 and sparc. The changes are mostly on the codegen level, with a few exceptions when we do access things outside of the heap that are uncompressed from the IR. Compressed oops are now also enabled with tiered.
