Add a testcase for PR10417 support for DW_OP_{stack|implicit}_value.

Currently XFAILS when gcc-vta detected, otherwise UNTESTED.

* testsuite/systemtap.base/vta-test.exp: New test harness.
* testsuite/systemtap.base/vta-test.c: New test program.
* testsuite/systemtap.base/vta-test.stp: New test script.
