[PATCH] xtensa: Refine constraint "T" to define_special_memory_constraint

[Takayuki 'January June' Suwa]

References to literal pool entries do not need to be reloaded or converted
to "(mem (reg X))" to load via base register.
gcc/ChangeLog:

        * config/xtensa/constraints.md (T):
        Change define_memory_constraint to define_special_memory_constraint.
