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.
This turns all jump table entries into deltas within the target
function because in the small memory model all code & static data must
be in a 4GB block somewhere in memory.
When the entries were a delta between the table location and a basic
block, the 32-bit signed entries are not enough to guarantee
reachability.
