3dc52575f0 slice_length: avoid implementation-defined division by negative number 
In CircuitPython (only), a the slice assignment to [-1👎-3] of an
ndarray of length 1 caused a crash.  This appears to be because in
CircuitPython, the internal pointer of an empty array was NULL rather than
pointing at some memory which happened to be valid and assignable.

This appears to be a corner case of how integer promotion rules work in C.
The expression `slice.stop - slice.start + (slice.step + correction)`
is type `unsigned long` and on a LP64 platform its value is
18446744073709551614.  This led to the function returning that this slice
had length 1 instead, during the automated tests.

By casting to signed types capable of holding indices and sizes, the
problem is corrected on both platforms.

f9fabc5079 Fix handling of negative indices 
I don't know why, but mp_seq_get_fast_slice_indexes adjusts "stop" in a
surprising way, and that led to the (remaining) differences in slicing
between ulab and built-in lists.

    // If the index is negative then stop points to the last item, not after it
    if (indexes->step < 0) {
        indexes->stop++;
    }

Call the underlying routine, mp_obj_slice_indices, instead.

7846b0c469 convolve: Optimize and special-case floats 
Special casing floats decreases runtime to about 50% (applying a 117-tap
filter to 512 points of data goes from 70ms to 32ms)

The top_n/bot_n calculations already meant that the a/c indices were
never out of range.  This decreases runtime further to about 15% of
original (11ms)

Timings done on an Adafruit Clue (nrf52840 at 64MHz)

It does of course increase code size somewhat.
