        * gcc.c-torture/execute/990119-1.c: Renamed to...
        * gcc.dg/990119-1.c: this, so it will only be tested once
        (it's a preprocessor test, it doesn't need to be run at
        multiple optimization levels).

The purpose is to reduce chatter in the testsuite output.  990119-1.c
is a test of a corner case in the preprocessor involving \-newline
and __LINE__.  cccp gets it wrong, but no one in their right mind
depends on the behavior, so it's not a big deal.  With this test in
c-torture/execute, it produces six failure notices and appears much
more important than it is.  Moving it to gcc.dg makes it produce just
one failure notice, and locates it with the rest of the odd corner
case tests.
