[BUG] Unexpected compiler failure with conversions between Scalar[DType].

[Drunte]

Bug description

When using a parameter DType in a function, the compiler sometimes fails to convert from Float64 to Scalar[DType]. See the code snippets below.

Steps to reproduce

• Include relevant code snippet or link to code that did not work as expected.
  snippet1:

fn f[type: DType](i: Int) -> None:
   constrained[type.is_floating_point(), "type failed to be a floating point type"]();
   var val: Scalar[type] = 1.0 / i; #fails to compile here
   #...

Whereas the following two snippets both work.

fn f[type: DType](i: Int) -> None:
   constrained[type.is_floating_point(), "type failed to be a floating point type"]();
   var val: Scalar[type] = 1.0;
   val /= i;
   #...

fn f[type: DType](i: Int) -> None:
   constrained[type.is_floating_point(), "type failed to be a floating point type"]();
   var val: Scalar[type] = rebind[Scalar[type]](1.0 / i);
   #...

The failure in snippet 1 is unexpected since the expression evaluates to Float64 which should be convertible to Scalar[DType], without the need for rebind. The failure is observed in both the stand alone compiler and the playground.
