97e169ac77 8145628: hotspot metadata classes shouldn't use HeapWordSize or heap related macros like align_object_size 
Use align_metadata_size, align_metadata_offset and is_metadata_aligned for metadata rather than align_object_size, etc.  Use wordSize rather than HeapWordSize for metadata.  Use align_ptr_up rather than align_pointer_up (all the related functions are ptr).
