The lowering for v2i64 is now guarded with hasDirectMove,
however, the current lowering can handle the pattern correctly,
only lowering it when there is efficient patterns and corresponding
instructions.
The original guard was added in D21135, and was for Legal action.
The code has evloved now, this guard is not necessary anymore.

This will currently accept the old number of bytes syntax, and convert
it to a scalar. This should be removed in the near future (I think I
converted all of the tests already, but likely missed a few).
Not sure what the exact syntax and policy should be. We can continue
printing the number of bytes for non-generic instructions to avoid
test churn and only allow non-scalar types for generic instructions.
This will currently print the LLT in parentheses, but accept parsing
the existing integers and implicitly converting to scalar. The
parentheses are a bit ugly, but the parser logic seems unable to deal
without either parentheses or some keyword to indicate the start of a
type.

An offset without a base isn't terribly useful but it's convenient to update
the offset without checking the value. For example, when breaking apart
stores into smaller units
