[PATCH] fix struct-layout-1 tests for Xtensa

[Bob Wilson]

With the default compile options, Xtensa has some limitations on code size that 
are exceeded by the struct-layout-1 tests.  Someday I hope to fix those 
limitations, but in the meantime, I'm getting tired of watching these tests 
fail.  For the g++.dg version of the test, it is easy to just add a dg-options 
line for Xtensa targets.  The gcc.dg version is missing Uros Bizjak's change for 
the g++.dg version (http://gcc.gnu.org/ml/gcc-patches/2008-02/msg00607.html) to 
avoid replicating the dg-options lines 3 times each, so I've ported that change 
over to the C version and then added the Xtensa options.

I tested this patch by doing an i686-pc-linux-gnu bootstrap and then running the 
C and C++ testsuites.  I verified that there were no regressions related to this 
change and that all the struct-layout-1 tests ran as expected.

OK to commit?
