Remove unneeded #ifdef SWIGs

Summary:
Some of these were present in files which should never be read by swig
(and we also had one in the interface file, which is only read by swig).
They are probably leftovers from the time when we were running swig over
lldb headers directly.

While writing this patch, I noticed that some of the #ifdefs were
guarding public functions that were operating on lldb_private data
types. While it wasn't strictly necessary for this patch, I made these
private, as nobody should really be accessing them. This can potentially
break existing code if it happened to use these methods, though it will
only break at build time -- if someone builds against an old header, he
should still be able to link to a new lldb library, since the functions
are still there.

We could keep these public for backward compatbility, but I would argue
that if anyone was actually using these functions for anything, his code
is already broken.
