Split out modsi3 and umodsi3 from the divsi3 file. This is so that
we don't get re-defined symbols in libc from libgcc in static linking.
Example: cc -pthread -static main-calls-pthread-create.c
add split files.
add new divsi3 related files.
add new files to fix static linking
split udivsi3 and divsi3 to fix static linking. This could be done better.
Fixes PR#47139
