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.
Mostsly these would fail due to trying to use SI with a flat
operation. Implementing global loads with MUBUF is more work than
flat, so these won't be handled in the initial load selection.
Others fail because store of s64 won't initially work, as the current
set of patterns expect everything to be turned into v2i32.
