[PATCH, OBVIOUS] rs6000: Remove redundant MEM_P predicate usage

[Peter Bergner via Gcc-patches]

While helping someone on the team debug an issue, I noticed some redundant
tests in a couple of our predicates which can be removed.  I'm going to
commit the following as obvious once bootstrap and regtesting come back
clean.

rs6000: Remove redundant MEM_P predicate usage

The quad_memory_operand and vsx_quad_dform_memory_operand predicates contain
a (match_code "mem") test, making their MEM_P usage redundant.  Remove them.

gcc/
        * config/rs6000/predicates.md (quad_memory_operand): Remove redundant
        MEM_P usage.
        (vsx_quad_dform_memory_operand): Likewise.
