[dev.unified] cmd/compile: set base.Pos when process assignDef in Unified IR

Browse source 
CL 410343 changes Unified IR to visit LHS before RHS/X in assign/for
statement. Thus, it needs to set base.Pos before processing assignee
expression, so invalid type can be reported with correct position.

Updates #53058
