The optimization that replaces inline markers with pre-existing instructions assumes that 'Prog' values produced by the compiler are still reachable after the assembler has run. This was not true on s390x where the assembler was removing NOP instructions from the linked list of 'Prog' values. This led to broken inlining data which in turn caused an infinite loop in the runtime traceback code. Fix this by stopping the s390x assembler backend removing NOP values. It does not make any difference to the output of the assembler because NOP instructions are 0 bytes long anyway. Fixes #40473.
