cmd/compile: disable use of new saturating float-to-int conversions
The new conversions can be activated (or bisected) with
-gcflags=all=-d=converthash=PATTERN
where PATTERN is either a hash string or n, qn, y, qy for
no, quietly no, yes, quietly yes.
This CL makes the default pattern be "qn" instead of the
default-default which is an efficient encoding of "qy".
Updates #75834
