            Bug ID: 22410
           Summary: Don't use CopyContext in RegisterContextWin
           Product: lldb

                OS: Windows NT

CopyContext is the only safe way to access a CPU's XSTATE, but it's only
available on Windows 7 and higher.  It is also the sole reason for requiring
the newest version of the Windows SDK.  For compatibility purposes, and since
we are not actually using XSTATE for any purpose yet, we should get rid of this
CopyContext stuff, which would make supporting Vista possible and reduce the
SDK version requirement.
