Blackfin: code to expand additional builtins

[Bernd Schmidt <bernds_cb1@t-online.de>]

[-- Attachment #1: Type: text/plain, Size: 502 bytes --]

This adds four more builtins.  Most of the code was there already, but
there was no entry in the bdesc_2arg table so we couldn't expand them.

There's also a new testcase (duplicated since it tests different things
at -O0 and -O2).
