These were included when the Fortran flag table was first created by
commit 10c91ded (ENH: add support for Intel Fortran Visual studio IDE,
2008-04-30, v2.8.0~2227), but they map to fields not actually supported
by the IDE.  Remove their table entries.

Instead use just `/debug:minimal` and `/debug:full` to control debug
information level in VS Intel Fortran.  Let flags like `/Z7` pass
through as raw additional options because they have no corresponding IDE
property and can be used to complement the supported options.
