[PATCH, testsuite]: Add fortran testcase for PR 36680

[Uros Bizjak]

Hello!

The testcase failed to compile with 4.4 with spill failure, but
compiles OK with 4.6+. Attached patch adds the test to gcc testsuite,
so the bug can be closed.

	PR target/36680
	* gfortran.dg/pr36680.f90: New test.

Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.

Uros.
