Test 'set print frame-info|frame-arguments presence'.

Updated tests to test the new options and new values.
Test the default for print_what in python frame filtering.
Updated the tests impacted by the default in python frame filtering
which is now consistent with the backtrace command.

2019-07-29  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* gdb.base/options.exp: Update backtrace - completion to
	new option -frame-info.
	* gdb.base/frame-args.exp: Test new 'frame-arguments presence'.
	Test new 'set print frame-info'.  Test backtrace -frame-info
	overriding 'set print frame-info'.
	* gdb.python/py-framefilter.exp: Test new 'frame-arguments presence'.
	Test new 'set print frame-info'.
	Verify consistency of backtrace with and without filters, with and
	without -no-filters.
	* gdb.python/py-framefilter-invalidarg.exp: Update to new print_what
	default.
