[test] Add tests for 64-bit division
On a 32-bit system, 64-bit division is implemented using the libgcc
functions provided in __udivmoddi4.c etc. Calls to these functions
are generated automatically by gcc, with a calling convention that is
somewhat empirical in nature. Add these self-tests primarily as a
check that we are using the correct calling convention.
