compiler: fix nil constant interface
...
A nil interface has no dynamic type (or: nil dynamic type). Don't try to
use the static type as the dynamic type, because these are different.

runtime/scheduler: make debugging easier + rename some functions
...
This shouldn't affect functionality but makes debugging a whole lot
easier. A scheduler is difficult so make it easy to debug.

nrf: fix sleep

at the nrfx update?). Change sleep behavior to be more correct.

Copy printfloat() from original runtime
...
I've tried writing my own, but I couldn't make it correct in all cases.
So just copy the one from upstream for now, hopefully to be replaced at
some point.
TODO: add a printfloat32() implementation, now it just casts to float64.
This will be useful for embedded systems that sometimes have float32 but
not float64.

interpreter: string concatenation

Sometimes strings are concatenated in a way that isn't const-propagated
by the SSA transformation (e.g. the result of a function call).
Concatenate them during init() interpretation.
