8a261b050c Remove the multicore trampoline and make the core 1 startup function generic
I managed to avoid the multicore trampoline by messing with the signature of the core 1 startup function.
While the first couple arguments to a function with the arm C abi are passed in registers, once they're filled up, the rest of the arguments go on the stack; so, I put some dummy arguments before the real arguments to force them to go onto the stack. That allows it to be used directly, without needing the trampoline to move the arguments from the stack to registers.

I also changed the startup function to be generic over the function type passed, which avoids the mess of dealing with `Core1Main` and fat pointers and all that.

402b7f1eb8 Use u32 instead of u64 division in clock calculations
This saves about 1kB of flash by removing
compiler_builtins::int::specialized_div_rem::u64_div_rem if
no other code uses u64 divisions.
