Get rid of lldb-dll-export.h and place the smarts of this into lldb-defines.h. 

Please do not add header files that are required in public APIs without first checking with us. This broke the LLDB builds at Apple because the lldb-dll-export.h wasn't included in the LLDB.framework and it was being included by public API header files.
