x64: Mask shift amounts for small types (#4752)

Browse Source 
* x64: Mask shift amounts for small types

* cranelift: Disable i128 shifts in fuzzer again

They are fixed. But we had a bunch of fuzzgen issues come in, and we don't want to accidentaly mark them as fixed

* cranelift: Avoid masking shifts for 32 and 64 bit cases

* cranelift: Add const shift tests and fix them

* cranelift: Remove const `rotl` cases

Now that `put_masked_in_imm8_gpr` works properly we can simplify rotl/rotr
