This patch makes adjustments to header file includes in lldbUtility based on recommendations by the iwyu tool (include-what-you-use). The goal here is to make sure that all files include the exact set of headers which are needed for that file only, to eliminate cases of dead includes (e.g. someone deleted some code but forgot to delete the header includes that that code necessitated), and to eliminate the case where header includes are picked up transitively. llvm-svn: 299676
