Scaling the timer on the system bus has a notable impact on
performance. So, scale the timer within the timer hardware itself.

The Trinamic stepper motor drivers are capable of reporting the
stepper phase - add support for using that capability to the
enddstop_phases module.

Only clear the internal sync_print_time flag if the code performs a
regular "lazy" flush of the look-ahead queue. This helps build the
look-ahead queue even when running internal scripts.

Now that "Klipper state" messages are proactively sent, it is
redundant to send the "preparing to restart" message.

It appears the sam3x8e has a primitive cache prefetch mechanism (it
prefetches 32 bytes at a time aligned to a 16 byte boundary).
Aligning the main loop in timer_dispatch_many() to a 16 byte boundary
significantly improves performance.

If sched_try_shutdown() is not inlined into timer_dispatch_many() it
can have a significant impact on benchmarks. (Even though the
function isn't called in practice, the call causes gcc to organize the
function differently.)

Some older versions of gcc need the __always_inline directive in order
to inline timer_read_time. Inlining that function is important for
performance on the stm32f1.

As long as timer_read_time() is inlined, I get better performance with
gcc -O2 optimization. The binary is also dramatically smaller and O2
better matches the other platforms.

It's possible for the code to stay in the timer irq for up to 100ms,
so serial irqs should have a higher irq priority to prevent them from
being starved. (The timer code disables irqs during event dispatch,
so serial irqs would only be permitted between events anyway.)

When a delta printer has different arm lengths or different endstop
positions then the homing position falls outside of the normal
printable area. Add a special check to the range checking code to
permit this move instead of homing to a position near the actual
homing position.

Commit b0d859f2 introduced a second_homing_speed parameter, and it
also changed the retract speed. Revert the retract speed change (use
homing_speed when the head retracts).

Commit b0d859f2 introduced a second_homing_speed parameter; that
parameter needs to also be constrained to the max_z_velocity.

Use the xor capability of the display to animate the glyphs, which
reduces the number of glyphs needed from 4 to 2. This should make it
easier to add future animations if desired.
