LEFT_AND_FORALL_CONV : conv
STRUCTURE
SYNOPSIS
Moves a universal quantification of the left conjunct outwards through a conjunction.
DESCRIPTION
When applied to a term of the form (!x.P) /\ Q, the conversion LEFT_AND_FORALL_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.
