use crt0's trap handler for exceptions during destructor execution
GPIO: rename interface registers
- INPUT_LO -> INPUT[0]
- INPUT_HI -> INPUT[1]
- OUTPUT_LO -> OUTPUT[0]
- OUTPUT_HI -> OUTPUT[1]
- backwards compatibility aliases are added to neorv32_legacy.h
provide global data types (unions) for subword accesses
rename atomic LR/SC wrappers:
- neorv32_cpu_load_reservate_word() -> neorv32_cpu_amolr()
- neorv32_cpu_store_conditional_word() -> neorv32_cpu_amosc()
- backwards compatibility aliases are added to neorv32_legacy.h

backwards compatibility aliases added to neorv32_legacy.h

without the A extension these functions would have blocked forever

for backwards compatibility
