Currently, the ABI analysis assigns parameter/result offsets to the fields of function *Type. In some cases, we may have an ABI0 function reference and an ABIInternal reference share the same function *Type. For example, for an ABI0 function F, "f := F" will make f and (ABI0) F having the same *Type. But f, as a func value, should use ABIInternal. Analyses on F and f will collide and cause ICE. Also, changing field offsets in ABI analysis has to be done very carefully to avoid data races. It has been causing trickiness/difficulty. This CL removes the change of field offsets in ABI analysis altogether. The analysis result is stored in ABIParamAssignment, which is the only way to access parameter/result stack offset now. Fixes #47317. Fixes #47227.
