I don't think I have enough expertise to concisely explain what every
relocation does.  I can at least put in e.g. what instructions each
static relocation applies to, and add snippets from the standard where
available.  Joseph, what is your preference?  FWIW, few relocation
values in ARM block have any comments at all.

Right, makes no sense to export the names.  The numbers are guaranteed
not to be allocated, but hardly anyone will call them this.

Whom I have now added to the loop.
