Add C++ support to Makefile, and proof-of-concept simple.cpp example

This is a work in progress based on @mikejac's work.
Missing:
* No 'new' operator.
* I don't think STL is currently supported.

unaligned_load.c: Added more naive_strcpy tests

Added tests for naive_strcpy using a variety of different regs, as execution time can depend on which register is being used.

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.

name for 'extras/i2c' is now just 'i2c')
