To keep cross-compiling straightforward, Cretonne shouldn't have any behavior that depends on the host. This renames the "Native" calling convention to "SystemV", which has a defined meaning for each target, so that it's clear that the calling convention doesn't change depending on what host Cretonne is running on.
