For purposes of dynamically calling code, I need the following layout
of the assembled code:

0x00: 16-byte header
0x10: entry point #1
0x20: entry point #2

I want to use the new align/skip instructions for this.  My code
generator currently looks like this:

        align (16)
        skip (16)
        jump label1
        align (16)
       jump entry2 ; or some other code

However, with setup, GNU lightning often "optimizes" the block order
so that entry1 is no longer at the correct offset.  How can I reliably
prohibit this?  Putting skip (1) after the second align (16) seems to
help in my experiments.
