Fix #4143: atan(0,minf) should be %pi.

Fix typo in atan2 simplifier where we were taking the realpart of x
instead of the realpart of y to handle the case of atan2(y,minf). Add
a comment that we're making atan2 continuous with the second quadrant
along the branch cut.

Add a test for this case and update the documentation to say that
we're continuous with second quadrant on the branch cut.

Change infsimp* (defined in compar.lisp) to check for a mapatom, not an atom. This change prevents an infinite loop that can happen when expressions such as a[inf] are passed to infsimp*. The function extra-simp (defined in limit.lisp) had a workaround for this bug--this change also eliminates the workaround in extra-simp.

Tested with SBCL 2.2.2 (Windows) and Clozure Common Lisp Version 1.12.2 (v1.12.2) WindowsX8664 for both the testsuite and the share testsuite.

In documentation for row and col, state that row result shares memory with argument,
and col result does not.

Inspired by discussion on mailing circa 2023-09-06: "Side-effects on matrices"
