Made symbol lookup in the expression parser more

robust:

- Now a client can specify what kind of symbols
  are needed; notably, this allows looking up
  Objective-C class symbols specifically.

- In the class of symbols being looked up, if
  one is non-NULL and others are NULL, LLDB now
  prefers the non-NULL one.
