[RFA] Add ix86 target to asm-source.exp test

[Michael Snyder <msnyder@cygnus.com>]

This is a minimal port of the asm-source test to the i[3456]86 target.
This runs successfully on a Linux x86 machine, but will probably need
some work to make it run on other ix86 platforms (esp. embedded).

The file "i386.inc" is appended at the end of the patch.

Andrew -- since Fernando is stepping down as testsuite maintainer, 
and since you've tinkered with asm-source, perhaps you could play
the role of second-pair-of-eyes?
