cmd/compile: do not change field offset in ABI analysis 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.
