Derek Hageman b8ef969d92 Generate intrinsic aliases directly
Using the full module structure generated by the intrinsics macro
interacts oddly with inlining on some optimization levels, causing
a duplicate identical function body to be generated.  This doesn't
affect performance, but it wastes space, so just declare the alias
directly which seems to cause the symbol to be aliased as it should
be.

Allow to start multiple state machines in sync (#301)
* add example of synchronized PIOs

* Synchronize state machines using WAIT IRQ instruction

* Use "irq wait 0" instead of "wait 1 irq 0"

This way, the initial value of the interrupt flag doesn't matter

* Start state machines synchronized without IRQ WAIT instruction

* Improve API

Add an rp2040 specific #[entry] macro. (#300)
* Add an rp2040 specific #[entry] macro.

This macro extends the one from cortex-m-rt by code to unlock
all spinlocks on boot.

* Idiomatic pointer arithmetic

Apply suggestion by @9names, improving address calculations.
(This doesn't change the generated code at opt levels 2 or "z".)

no other code uses u64 divisions.
