tricks to get types to resolve. I did this by correctly including the correct files: stdint.h and all lldb-*.h files first before including the API files. This allowed me to remove all of the hacks that were in the lldb.swig file and it also allows all of the #defines in lldb-defines.h and enumerations in lldb-enumerations.h to appear in the lldb.py module. This will make the python script code a lot more readable. Cleaned up the "process launch" command to not execute a "process continue" command, it now just does what it should have with the internal API calls instead of executing another command line command. Made the lldb_private::Process set the state to launching and attaching if WillLaunch/WillAttach return no error respectively. llvm-svn: 115902
