Maps with constant keys are broken

[gechandesu]

Describe the bug

If the map keys are constants the map breaks and has only two elements of the declared ones — the first and the last. The keys themselves are incorrect.

Reproduction Steps

const bit = f64(1)
const nibble = bit * 4
const bytes = bit * 8
const kb = bytes * 1000
const mb = kb * 1000

const units_map = {
	bit: 'bit'
	nibble: 'nibble'
	bytes: 'byte'
	kb: 'kB'
	mb: 'MB'
}

fn main() {
	println(units_map.len)
	println(units_map)
}

Expected Behavior

Output:

5
{1.0: 'bit', 4.0: 'nibble', 8.0: 'byte', 8000.0: 'kB', 8.e+06: 'MB'}

Current Behavior

Output:

2
{1.0: 'bit', 0.0: 'MB'}

Additional Information/Context

Issue in example above reproduces with any numberic primitive type except int.

Also the following code works:

const k1 = f64(1)
const k2 = f64(2)
const k3 = f64(3)
const k4 = f64(4)
const k5 = f64(5)

const my_map = {
	k1: 'first'
	k2: 'second'
	k3: 'third'
	k4: 'fourth'
	k5: 'fifth'
}

fn main() {
	assert my_map.len == 5
	assert my_map == {1.0: 'first', 2.0: 'second', 3.0: 'third', 4.0: 'fourth', 5.0: 'fifth'}
}

But if a arithmetic operations appears in a constant, it breaks the map:

const k1 = f64(1)
const k2 = f64(2 * 2)
const k3 = f64(3)
const k4 = f64(4)
const k5 = f64(5)

const my_map = {
	k1: 'first'
	k2: 'second'
	k3: 'third'
	k4: 'fourth'
	k5: 'fifth'
}

fn main() {
	assert my_map.len == 5
	assert my_map == {1.0: 'first', 2.0: 'second', 3.0: 'third', 4.0: 'fourth', 5.0: 'fifth'}
}
