wasm: execute an 'unreachable' trap inst on panic

compiler: check slice cap instead of len during slicing
...
When doing a slice operation on a slice, use the capacity value instead
of the length. Of course, for strings and arrays, the slice operation
checks the length because there is no capacity. But according to the
spec, this check should be based on cap for slice instead of len:
> For slices, the upper index bound is the slice capacity cap(a) rather
> than the length.

It is allowed to index with an int64 even on a 32-bit platform, so we
have to handle that case. But make sure the normal case isn't penalized
by using 32-bit numbers when possible.

nrf: fix off-by-one in modulo of runtime.ticks
...
This code:
foo & 0xffffff
Is equivalent to this code:
foo % 0x1000000
However, to drop the high 8 bits, this calculation was used:
foo % 0xffffff
This is far more expensive (and incorrect), as it needs an actual modulo
operation which increases code size and probably reduces speed on a
Cortex-M4 and needs library functions for a Cortex-M0 increasing code
size by a much bigger amount.
