LEFT_AND_EXISTS_CONV
Conv.LEFT_AND_EXISTS_CONV : conv
Moves an existential quantification of the left conjunct outwards through a conjunction.
When applied to a term of the form (?x.P) /\ Q, the conversion
LEFT_AND_EXISTS_CONV returns the theorem:
|- (?x.P) /\ Q = (?x'. P[x'/x] /\ Q)
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 (?x.P) /\ Q.
