FreeBSD core files have no section table and thus LLDB's OS and vendor
detection logic does not work. If we encounter such an ELF file, update
an unknown OS to match the host.
This is not really the correct way to handle this, but more extensive
rework of ObjectFileELF will be needed and this change restores cross-
arch core debugging until that can be completed.
Highlights include:
- Support hardware watchpoints on FreeBSD
(r201706)
- Improved unwinding through hand-written assembly functions
(r201839)
- Handle DW_TAG_unspecified_parameters for variadic functions
(r202061)
- Fix Ctrl+C interrupting a running inferior process
(r202086, r202154)
- Various bug fixes, including to the remote GDB protocol client

ludes minor changes relative to upstream, for compatibility with
FreeBSD's in-tree LLVM 3.3:
- Reverted LLDB r191806, restoring use of previous API.
- Reverted part of LLDB r189317, restoring previous enum names.
- Work around missing LLVM r192504, using previous registerEHFrames API
(limited functionality).
- Removed PlatformWindows header include and init/terminate calls.
