Keith Randall af7f067e0d cmd/compile: tighten bounds for induction variables in strided loops
for i := 0; i < 9; i += 3

Currently we compute bounds of [0,8]. Really we know that it is [0,6].

CL 415874 computed the better bound as part of overflow detection.
This CL just incorporates that better info to the prove pass.

R=go1.20
