Merge pull request #3026 from lewurm/is-call-macro

[mini] small improvements around `MONO_IS_CALL` macro and `local-prop`

showed up in vtunes when running
```
./mono/mini/mono-sgen --stats -O=all --aot=threads=1,asmonly ~/work/benchmarker/tests/fsharp/lib/bootstrap/4.0/FSharp.Compiler.dll
```

also, I think when `OP_DYN_CALL` was introduced, it wasn't added to the `MONO_IS_CALL` macro. @vargaz, what do you think?
