Also add a V8_COMPRESS_POINTERS_IN_SHARED_CAGE define when pointer compression is enabled. This CL is to get performance numbers for reserving an extra register. There is no actual pointer cage yet, and the base register will always have the same value as the root register. The pointer decompression code is switched to using the base register instead of the root register.
