Calling generic function which can't resolve typename should print better error

[MaxGraey]

function test<T>(x: i32): i32 {
  return x << sizeof<T>();
}
test(1); // call function without specify typename

Output:

ERROR: AssertionError: assertion failed

r.assert@https://assemblyscript.github.io/assemblyscript/dist/assemblyscript.js:2:134139
...

Expected:

ASxxxx: Can't resolve typename for `test`
