cmd/compile: remove some write barriers for stack writes
This, along with CL 30140, removes ~50% of stack write barriers
mentioned in issue #17330. The remaining are most due to Phi and
FwdRef, which is not resolved when building SSA. We might be
able to do it at a later stage where Phi and Copy propagations
are done, but matching an if-(store-store-call)+ sequence seems
not very pleasant.
Updates #17330.
