Matthew Dempsky 89b44b4e2b cmd/compile: recognize reassignments involving receives ...

Previously, reassigned was failing to detect reassignments due to
channel receives in select statements (OSELRECV, OSELRECV2), or due to
standalone 2-value receive assignments (OAS2RECV). This was reported
as a devirtualization panic, but could have caused mis-inlining as
well.

Fixes #43292.
