[m-rev.] diff: hide documentation for more experimental grade components

[Julien Fischer]

Hide documentation for more experimental grade components.

compiler/options.m:
 	Hide the documentation for the .tsw and .tsc grade components.
 	They are experimental and not useful for non-developers.

 	Fix an error introduced in my last change: hlc is also a valid base
 	grade for '--target c'.

doc/user_guide.texi:
 	Conform to the above change.

Julien.
