cmd/internal/obj/ppc64: don't remove NOP in assembler Previously, the assembler removed NOPs from the Prog list in obj9.go. NOPs shouldn't be removed if they were added as an inline mark, as described in the issue below. Fixes #40689 Once the NOPs were left in the Prog list, some instructions were flagged as invalid because they had an operand which was not represented in optab. In order to preserve the previous assembler behavior, entries were added to optab for those operand cases. They were not flagged as errors before because the NOP instructions were removed before the code to check the valid opcode/operand combinations.
