Ludovic Courtès 74abae04aa Baseline compiler no longer swaps rsh/lsh when transforming ash calls.
Reported by Marius Bakke <marius@gnu.org>
at <https://issues.guix.gnu.org/50696>.

Previously, the baseline compiler would incorrectly emit a right shift
when for, say, (ash x 2), and a left shift for (ash x -2).

* module/language/tree-il/compile-bytecode.scm (canonicalize): When Y is
negative, emit 'rsh', not 'lsh'.
* test-suite/tests/numbers.test ("ash at -O1"): New test.
