Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hook
The SVE patches change the size of a machine_mode from a compile-time
constant to a runtime invariant. However, target-specific code can
continue to treat the modes as constant-sized if the target only has
constant-sized modes.
The main snag with this approach is that target-independent code still
uses macros from the target .h file. This patch is one of several that
converts a target macro to a hook.
