Fix bad memory access in NMI handler
...
CallNMIExceptionHandler was saving/restoring registers to the wrong offsets,
causing it to potentially corrupt the first two slots of the
LoadStoreErrorHandler's save area.

Remove the unaligned load handler to its own source file as it was getting quite complex
...
The downside here is needing to use #include so the 'beq' in the
exception vector can land on it directly, save an instruction.
There might be a better way to do this, but it seems hard to "curate"
the order that symbols appear in each section.

Exception vector address must be 256 byte aligned

Not actually a problem with the current linker script as the address is
predetermined there at start of IRAM, but might as well be accurate
about it.
