7c8c258cdd coff: Fix section alignment computation 
Section alignment is broken due to not being
direct "align -> power of two set" mapping but
rather including second addition operation.

Fix it by introducing coff_sectalign_flags helper.
This also allow us to use this helper for getting
rid of open coded computation as well.

1f3db76ee9 smartalign.mac: align macro should align a segment as well 
This change may have backward compatibility issue but
most probably the sane program never used sections with
base address less then instruction alignment.

Note that alignment may only increase which means if a
section is aligned on 2^5 the align 2^4 will not affect
the section.

(introduced by commit bb0745f). The former just ignore
any other options/values except first one.
