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.
Scheduler will try to retrieve the offset and base addr to determine if two
loads/stores are disjoint memory access. PowerPC failed to handle this for
frame index which will bring extra memory dependency for loads/stores.

Implement passing of ByVal formal arguments when the argument is passed
partly in the argument registers, with the remainder of the argument
passed on the stack.

Any or all the argument registers can be used to pass a byval formal
argument, with the limitation that the argument must fit in the
available registers (ie: is not split between registers and stack).
