Scott McMurray 0601f0c66d De-LLVM the unchecked shifts [MCP#693]
This is just one part of the MCP, but it's the one that IMHO removes the most noise from the standard library code.

Seems net simpler this way, since MIR already supported heterogeneous shifts anyway, and thus it's not more work for backends than before.
