compile-time f32, f64 operations are now correctly lossy
...
previously we used the bigfloat abstraction to do all
compile-time float math. but runtime code and comptime code
are supposed to get the same result. so now if you add a
f32 to a f32 at compile time it does it with f32 math
instead of the bigfloat. float literals still get the
bigfloat math.

bit shifting safety

integer with log2 bit width of other param

shift amount >= bit width with the type system
