The code didn't take into account that x and y might be different types.
(This bug was not actually harmful; type coercion allowed the code to
compile even with the wrong type. The float would be silently splatted
into a vec and the rest of the code would work as-is.)

4x4 was dividing a matrix by a scalar - this isn't allowed, multiply by
the scalar's inverse instead.
The types in the signature were derived from type.name(), which wasn't
applying the half->float re-mapping.
Finally, use raw strings so the resulting shader code isn't all crammed
on one line.

When we determine that a function only contains a single return
statement and it is at the top level (i.e. not inside any scopes),
there is no need to create a temporary variable and store the
result expression into a variable. Instead, we can directly replace
the function-call expression with the return-statement's expression.
Unlike my previous solution, this does not require variable
declarations to be rewritten. The no-scopes limitation makes it
slightly less effective in theory, but in practice we still get
almost all of the benefit. The no-scope limitation bites us on
structures like
@if (true) {
return x;
} else {
return y;
}
Which will optimize away the if, but leave the scope:
{
return x;
}
However, this is not a big deal; the biggest wins are single-line
helper functions like `guarded_divide` and `unpremul` which retain
the full benefit.

Previously, coercion between a signed type and an unsigned type was
treated as "no cost" because these types shared the exact same priority.
This meant that we couldn't choose the proper overload with function
calls that only differed in signed-ness, like:
void fn(int4 x);
void fn(uint4 x);
So we would always choose the int4 version since we encountered it
first. Now, we can choose the correct overload; signed types now have
a slightly elevated priority over unsigned types, allowing coercion
costs to work normally.
Also added some comments to `determineFinalTypes` while trying to see
if that needed some improvements as well, but this turned out to be
a red herring--it didn't need any functional changes.
