[PATCH, testsuite]: Use -O0 for gcc.dg/plugin/poly-int-07_plugin.c ...

[Uros Bizjak]

... as is the case with all other
gcc.dg/plugin/poly-int-0{1,2,3,4,5,6}_plugin.c testcases. This lowers
testcase wall time from 4min 45 sec to 1min 17sec on a slow target.

    * gcc.dg/plugin/poly-int-07_plugin.c (dg-options): Use -O0.

Tested on alphaev68-linux-gnu, committed to mainline as obvious.

Uros.
