Toon Verwaest 8109b4795e [ptr-compr] Remove unnecessary decompression in kArchStoreWithWriteBarrier 
The object itself is already decompressed, and we're simply re-decompressing by
nuking the upper bits through sign extension.

Additionally this CL changes the branchless decompression sequence on x64 to be
cmov-based since that's shorter and faster. It's still slower than branchful
though, so we likely won't use it.
