tracker issue : CF-4202194

Problem Description:

If you use `final` for a variable in a function, to function scope it you need to do `final var myvar` to stop it bleeding. The extra `var` seems unnecessary to me. I'd like it if the foo example below worked as the bar one does.

```
<cfscript>
function foo(){
  final a = "One"
  return a
}
function bar(){
  final var b = "Two"
  return b
}

x = foo()
y = bar()

writeOutput("IsNull(a): #isNull(a)#<br>") // NO
writeOutput("IsNull(b): #isNull(b)#<br>") // YES

writeDump([x,y])
</cfscript>
```

Steps to Reproduce:

Run this:
https://trycf.com/gist/a677906474c0912d0838728dbd5944f1/acf2018?theme=monokai

Actual Result:

Without `var` the variable bleeds.

Expected Result:

`final` should imply `var` so that the variable does not bleed.

Any Workarounds:

Use `final var`.
