6885308: The incorrect -XX:StackRedPages, -XX:StackShadowPages, -XX:StackYellowPages could cause VM crash
Summary: Test minimal stack sizes given (also fixed linux compilation error)

Summary: GC workers now recognize an intermediate transient state of blocks which are allocated but have not yet completed initialization. blk_start() calls do not attempt to determine the size of a block in the transient state, rather waiting for the block to become initialized so that it is safe to query its size. Audited and ensured the order of initialization of object fields (klass, free bit and size) to respect block state transition protocol. Also included some new assertion checking code enabled in debug mode.
