RIGHT_OR_FORALL_CONV : conv
STRUCTURE
SYNOPSIS
Moves a universal quantification of the right disjunct outwards through a disjunction.
DESCRIPTION
When applied to a term of the form P \/ (!x.Q), the conversion RIGHT_OR_FORALL_CONV returns the theorem:
   |- P \/ (!x.Q) = (!x'. P \/ (Q[x'/x]))
where x' is a primed variant of x that does not appear free in the input term.
FAILURE
Fails if applied to a term not of the form P \/ (!x.Q).
