Remove the extra condition where we only kept constraints if the new
TyperState does not contain new type variables, this used to be needed
to compile tests/pos/i6682a.scala with -Ycheck:all, otherwise we would
get:
assertion failed: Types differ
Original type : (y: PolyFunction{apply: [T](y: T): y.type => Int}): y.type => Int
After checking: (y: PolyFunction{apply: [T](y: T): y.type => Int}): y.type => Int
But it turns out that 55a223c fixed
that.
Fixes scala#12126.
