        * config/i386/i386.md (truncdfsf2): Don't create stack temp when
        using sse math only.  Use truncdfsf2_with_temp.
        (truncdfsf2_with_temp): New.
        (truncdfsf_fast_i387): Rename from truncdfsf2_noop.  Add memory
        output alternative.
        (truncdfsf_mixed): Rename from truncdfsf2_1_sse.  Compress duplicate
        alternatives.
        (truncdfsf_fast_sse): Rename from truncdfsf2_2.  Remove f alternative.
        (truncdfsf2_3, truncdfsf2_sse_only): Remove.
        (truncdfsf_i387): Rename from truncdfsf2_1.  Compress duplicates.
        (truncdfsf_fast_mixed): New.
        (truncdfsf splitters): Remove all except the 387 load/store split.
        (truncxfsf2_1, truncxfdf2_1): Unify enable constraint with
        respect to TARGET_SSE2, TARGET_80387, TARGET_SSE_MATH and
        TARGET_MIX_SSE_I387.
        (*truncxf{s,d}f2_1): Rename to *truncxf{s,d}f2_mixed.
        (truncxf{s,d}f2_noop) Rename to truncxf{d,s}f2_i387_noop.
