RIGHT_OR_EXISTS_CONV : conv

SYNOPSIS
Moves an existential quantification of the right disjunct outwards through a disjunction.

DESCRIBE
When applied to a term of the form P \/ (?x.Q), the conversion RIGHT_OR_EXISTS_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).
