[PATCH v2 0/3] riscv: Fix build against binutils 2.38

[Heinrich Schuchardt]

Compiling for RISC-V with binutils 2.38 and binutils 2.37 requires
different build flags. This is fixed by Alexandre Ghiti's patch.
But building qemu-riscv32*_defconfig fails due to missing
implementations of __ashldi3, __lshrdi3. Add these functions and
a unit test for them.

  riscv: implement __ashldi3, __lshrdi3
  test: test bit shift operations on RISC-V
