On certain architectures (like AARCH64) padding may be inserted between the locals and the rest of the stack frame in order to keep the frame pointer 16-byte-aligned.

This padding is currently not freezed, instead freezing of a single interpreter stack frame is done using two separate copy_to_chunk() calls (see recurse_freeze_interpreted_frame). Likewise, thawing is done using two separate copy_from_chunk() calls.

This poses a bit of a problem when trying to relativize stack addresses in interpreter frames (JDK-8289296). Since relative offsets may need to be changed during freezing and thawing.

By both freezing and thawing the padding we remove the need to change any relative offsets in runtime.
