7005241: C1: SEGV in java.util.concurrent.LinkedTransferQueue.xfer() with compressed oops
...
Implementation of the CAS primitive for x64 compressed oops was incorrect. It kills rscratch2 register (r11), which is allocatable in C1. Also, we don't need to restore cmpval as it's never used after that, so we need only one temporary register, which can be scratch1.

7003554: (tiered) assert(is_null_object() || handle() != NULL) failed: cannot embed null pointer
...
C1 with profiling doesn't check whether the MDO has been really allocated, which can silently fail if the perm gen is full. The solution is to check if the allocation failed and bailout out of inlining or compilation.

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.
