Using `TailCall` diagnostic attribute on non tailcall rec function does not generate warning on Visual Studio Error List pane

Please provide a succinct description of the issue.

**Repro steps**

Steps required to reproduce the problem:

1. Use this code on any .fs file and compile it:

```
[]
let rec private sumListTailRecHelperWithTailcallDiagnostic accumulator xs =
match xs with
| [] -> accumulator
| y::ys -> sumListTailRecHelper (accumulator+y) ys

/// This example computes the sum of a list of integers using recursion.
[]
let rec sumList xs =
match xs with
| [] -> 0
| y::ys -> y + sumList ys
```
2. Watch the output pane for Build and the Error List pane.

Is this intentional? As usually compiler warning is also always shown on Error List pane.

**Expected behavior**

Both Error List pane and the Output pane of Build should show the warning of using TailCall attribute on non tailcall rec function.

**Actual behavior**

Only Built output show compiler warning, whereas the Error List do not show the warning:


**Known workarounds**

As far as I know, none. I have tried to clear the compiler output folder, and compile again using clean rebuild.
