I've just updated with the changes (and softfp) and it would appear to be working ok.

Now we have some hardware FP support, I wonder if it might be worth implementing at least __aeabi_d2f and __aeabi_f2d if only as static functions added to what's compiled (which should get compiled out if not used) so that at least it's possible to convert to/from doubles for Espruino?

I can see the Raspberry Pi Pico seems to have optimised implementations?

For some reason the following compiles fine on my local EspruinoCompiler, but fails on the online one:
```
let c = E.compiledC(`
// int boop(double)

int boop(double d) {
  return float(d) * 3;
}
`);

print('boop:', c.boop(3.5));
```
Maybe it's a different GCC version? arm-none-eabi-gcc -v gives me:
gcc version 10.3.1 20210824 (release) (GNU Arm Embedded Toolchain 10.3-2021.10)

I think fixing it on the online one is just a matter of adding cflags += "-lgcc "; but I can't test that here. It doesn't increase the binary size unnecessarily and is much better than messing with inline assembly.
