Dmitry Antipov 6bba2ae43e lib: kunit: add tests for __ashldi3(), __ashrdi3(), and __lshrdi3() 
Add KUnit tests for '__ashldi3()', '__ashrdi3()', and '__lshrdi3()' helper
functions used to implement 64-bit arithmetic shift left, arithmetic shift
right and logical shift right, respectively, on a 32-bit CPUs.

Tested with 'qemu-system-riscv32 -M virt' and 'qemu-system-arm -M virt'.
