S/390: Make tests expect column numbers in RTL output

S/390: Make tests expect column numbers in RTL output

RTL output now includes column numbers in addition to line numbers,
like this:

  "gcc/testsuite/gcc.target/s390/md/andc-splitter-1.c":16:1

This confuses some S/390 tests.

gcc/testsuite/ChangeLog:

	* gcc.target/s390/md/andc-splitter-1.c: Add colon to
