  Hi,

To keep the previous refactoring patch not need to
re-generate fusion.md and make the review easier,
I didn't merge this patch into the previous one.

But I think this one can help to make the subroutine
gen_logical_addsubf_scalar more clear, by separating
logical-logical and add-logical handlings into two
different loops.  It needs to regenerate fusion.md,
since add-logical type definitions would have their
own continuous area (it needs some rearrangments).

Bootstrapped and regtested on powerpc64le-linux-gnu P10.

Any comments are highly appreciated.

BR,
Kewen
