actually, it wasn't a bug; the compiler just optimized a statement away
until it was declared volatile. inserting a no-op assembler instruction
to make it more obvious what's going on
includes minor refactoring in example code and modification of how the
generic and the tinygecko specific vector.h go together (bringing it in
line with stm32/f1's memorymap.h)
