lldb should warn when dSYM does not match the binary.

o Symbols.cpp:

  Emit a warning message when dSYM does not match the binary.

o warnings/uuid:

  Added regression test case.

o lldbtest.py:

  Modified to allow test case writer to demand that the build command does not begin
  with a clean first; required to make TestUUIDMismatchWanring.py work.
