Adrian Prantl f20d567633 Fix the hardcoded Swift AST section / segment name for Mach-O ...

to match the one specified in LLVM's Mach-O parser.
Otherwise LLDB could not possibly find it!

This name is used by the swift -modulewrap subcommand, which is currently unused
on Darwin, and primarily intended for use under Linux. However, it may be useful
to better support static archives (.a) files with Swift debug info in the
future. To fully support this, dsymutil and LLDB need to know to look for Swift
AST sections in Mach-O objects other than .dSYM bundled.

Implementation note: It would be nice to get the section name out of libObject,
but with the current architecture this needs a major refactoring that didn't
seem justified, given that there is an end-to-end test to prevent such a mishap
in the future.
