  [RISCV] Store Log2 of EEW in the vector load/store intrinsic to pseudo lookup tables. NFCI

This uses 3 bits of data instead of 7. I'm wondering if we can use
bitfields for the lookup table key where this would matter.

I also name the shift_amount template to log2 since it is used
with more than just an srl now.
