TARGET_ABSOLUTE_BIGGEST_ALIGNMENT is documented to be the largest
alignment possible for any type or variable, and defaults to
BIGGEST_ALIGNMENT.  But MAX_OFILE_ALIGNMENT is typically much larger
than BIGGEST_ALIGNMENT, and is documented as the limit for __attribute
((aligned)).  Shouldn't it be considered in the default for
absolute_biggest_alignment?  But if we make that change, I expect that
your ACCEL_COMPILER streamer-in change would become a no-op.  What was
that change intended to accomplish?  I'm not finding anything about it
in gcc-patches.
