This patch enables extending loads for fixed length SVE code generation.

There is a slight regression here in the mulh tests; since these tests
load the parameter and then extend it these are treated as extending
loads which are merged, preventing the mulh instruction from being
generated. As this affects scalable SVE codegen as well this should be
addressed in a separate patch.
