aarch64: Update reg-costs to differentiate between memmove costs
This patch introduces a struct to differentiate between different memmove costs
to enable a better modeling of memory operations. These have been modelled for
-mcpu/-mtune=neoverse-v1/neoverse-n1/neoverse-n2/neoverse-512tvb, for all other
tunings all entries are equal to the old single memmove cost to ensure the
behaviour remains the same.
