These do not add any value to the analysis other than duplicating some
reports
in whole-program analysis, as the intermediate linking steps are only
used to
build the symbol table.

A significant reduction in wallclock time can be seen for both arm64
and x86_64 jobs,
with no impact on correctness as far as I'm aware.
Yes, a very nice improvement. I suspect this wants backporting to
stable trees too?
Perhaps. Is the rate of analysis significant there?

Why the difference in suffix in the regex? Slightly rhetorical because
it's the full link address so includes an x for 0x.
But, the two regexs for suffixes really ought to be the same, so I
suppose we should exclude .* for xen_syms too?
Fine with me.
For the sake of clarity, do the names xen_efi and xen_syms want a _tmp
or _intermediate suffix, just to make things a bit clearer?
