Switch gdb's TRY/CATCH to sjlj again
We don't currently handle the case of gdb's readline callback throwing
gdb C++ exceptions across a readline that wasn't built with
-fexceptions. The end result is:
(gdb) whatever-command-that-causes-an-error
terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
Aborted
$
Until that is fixed, revert back to sjlj-based exceptions again.

* common/common-exceptions.h (GDB_XCPT_TRY): Add comment.
(GDB_XCPT): Always define as GDB_XCPT_SJMP.
