Title: dropped reporting of mov[s] r0, r0 as NOP

Currently `mov[s] r0, r0` is reported as a `I_NOP` but `movs` is different from a `nop` and can require special treatment.
Consider the following example from `libc` that shows how a `movs r0, r0` is useful.

```
ENTRY(gettid)
.save {r4, r7}
stmfd sp!, {r4, r7}
ldr r7, =__NR_gettid
swi #0
ldmfd sp!, {r4, r7}
movs r0, r0
bxpl lr
b __set_syscall_errno
```
