7007229: Fix warnings with VS2010 in compressedStream.cpp
Summary: An interference between a fix for 6993125 and disabled optimization in \
compressedStream.cpp produces a warning with VS2010. Disable the warning for the code \
                fragment for which the optimizations are disabled.

6985015: C1 needs to support compressed oops
Summary: 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.

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

7005241: C1: SEGV in java.util.concurrent.LinkedTransferQueue.xfer() with compressed \
                oops
Summary: 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.

7000559: G1: assertion failure !outer || (full_collections_started == \
                _full_collections_completed + 1)
Summary: The concurrent marking thread can complete its operation and increment the \
full GC counter during a Full GC. This causes the nesting of increments to the start \
and end of Full GCs that we are expecting to be wrong. the fix is for the marking \
thread to join the suspendible thread set before incrementing the counter so that \
it's blocked until the Full GC (or any other safepoint) is finished. The change also \
                includes some minor code cleanup (I renamed a parameter).
