An internal test failed on a riscv64-elf cross build because
Inferior.search_memory returned a negative value. I tracked this down
to to use of PyLong_FromLong in infpy_search_memory. Then, I looked
at other conversions of CORE_ADDR to Python and fixed these as well.
I don't think there is a good way to write a test for this.
