The r117616 check in broken these two test cases:

1. FoundationDisassembleTestCase.test_simple_disasm_with_dsym; and
2. FoundationDisassembleTestCase.test_simple_disasm_with_dwarf

the reason being the test was issuing 'disassemble' command to disassemble the current
frame function when stopped.  The 'disassemble' command worked previously but it was a
result of bad option specification.

Fix the disassemble command so that it will require 'disassemble -f' for disassembly of
the current frame function.
