Real and Imag builtin functions cause parsing errors

[149-code]

The following code results in a parser error where the builtins 'real' and 'imag' autocast into the wrong data type. The following code produces there error message: Error: '3.2' truncated to 'i8', got 3.200000 fmt.println(i8(real(x) / 3.2)).

package main

import "core:fmt"

main :: proc()
{
	x: complex128 = 10

	fmt.println(i8(real(x) / 3.2))
}

Note that this doesn't happen with other functions for example the following code produces the expected result

package main

import "core:fmt"

my_func :: proc(x: complex128) -> f64
{
	return real(x)
}

main :: proc()
{
	x: complex128 = 10

	fmt.println(i8(my_func(x) / 3.2))
}
