    alpha: Introduce target specific store_data_bypass_p function [PR105209]

    This patch introduces alpha-specific version of store_data_bypass_p that
    ignores TRAP_IF that would result in assertion failure (and internal
    compiler error) in the generic store_data_bypass_p function.

    While at it, also remove ev4_ist_c reservation, store_data_bypass_p
    can handle the patterns with multiple sets since some time ago.
