drop code emitting store_direct and load_direct
produce shorted code for adc without setflags
make emitted code for add shorter

compiler optimizes large switch-case so it's much faster that linear scan
drop ENABLE_STORELOAD_TRACING
removing usage of aa()
further aa() removal
fix signess warninig
print less debug info on sigaction
add preprocessor define TRACING_PROXY_DURATION governing proxy duration measure
add TRACING_CHECK_PROXY_R13
new additional_function
remove remaining use of aa()
make APSR local struct
make registers r4-r12,r14 local variables
use union aliasing instead of type punning
make C, V, N, Z unsigned
calculate and show code coverage
make some variables static
do close bfd
