Georgia Kouveli a63f045c3e [arm64] Update BuiltinContinuation frames for jssp alignment. 
Adds some necessary padding to ensure the frame is 16-byte aligned.
We don't yet consider the bailout state, which will be handled separately.

This patch also improves the code generated for ContinueTo*Builtin* stubs.

Finally, it adds a test that checks the return value for Array.map in
the case where a LAZY deopt results in a topmost builtin continuation
frame - this is easy to break if the padding for the result is done
incorrectly in NotifyBuiltinContinuation, but was not detected by existing
tests.
