The old code was broken and led to a HardFault in a rather convoluted
way:
1. The CFA offset was incorrect, in fact it was not aligned (the stack
is supposed to always be aligned to 4 bytes at least).
2. This unaligned size was then used for stack size calculations.
3. A stack that wasn't a multiple of 4 was allocated.
4. The calleeSavedRegs struct (in `(internal/task.state).archInit`) was
not correctly aligned.
5. Writing to this struct resulted in a HardFault.
