[testsuite] Skip gdb.trace/range-stepping.exp test case if not supported

  Hi all,

Tracepoints and range stepping are independent features.  This patch
skips the gdb.trace/range-stepping.exp test case if the target does not
support range stepping.

Thanks,
Pierre

gdb/testsuite/ChangeLog:

	* gdb.base/range-stepping.exp (gdb_range_stepping_enabled): Move
	* lib/range-stepping-support.exp (gdb_range_stepping_enabled):
	... to here.
	* gdb.trace/range-stepping.exp: Check that the target supports
	range stepping.

We write changelog for such moving like this,

	* gdb.base/range-stepping.exp (gdb_range_stepping_enabled): 
        Move it to ...
	* lib/range-stepping-support.exp (gdb_range_stepping_enabled):
	... here.
