Attached to this message, please find the testcase for underflow
control for large types. I was using this test to check for support of
large types on x86_64 and alpha. I can confirm that neither target
supports underflow control for large types, but nevertheless I think
the test could be used as a negative test for
ieee_support_underflow_control.

    * gfortran.dg/ieee/large_4.f90: New test.

Tested on x86_64-linux-gnu {,-m32}  and alphaev68-linux-gnu.

OK for mainline?
