        (truncxf<mode>2_i387_noop_unspec): New insn pattern.
        (sqrt_extend<mode>xf2_i387): New insn pattern.
        (sqrt<mode>2): For non-SSE sqrt, emit sqrt_extend<mode>xf2_i387
        insn and truncate result back to original mode using
        UNSPEC_TRUNC_NOOP truncation.
        (*sqrt<mode>2_sse): Implement using SSEMODEF mode macro and
        ssemodefsuffix mode attribute.
        (*sqrtsf2_mixed, *sqrtsf2_i387, *sqrtdf2_mixed, *sqrtdf2_i387)
        (*sqrtextendsfdf2_i387, *sqrtextendsfxf2_i387)
        (*sqrtextenddfxf2_i387): Remove insn patterns.

        (fmodsf3, fmoddf3, remaindersf3, remainderdf3): Use noop
        truncation patterns.

        reg-stack.c (get_true_reg): Handle UNSPEC_TRUNC_NOOP.
