Revert of Modify LineBench for drawing straight line (patchset #3 id:40001 of https://codereview.chromium.org/1936153002/ )

Reason for revert:
         for (int i = 0; i < loops; i++) {
 54             canvas->drawPoints(SkCanvas::kLines_PointMode, PTS, fPts, paint);	 68             canvas->drawLine(fStartPts[i].x(), fStartPts[i].y(), fEndPts[i].x(), fEndPts[i].y(), pai
    nt);

This change means we index arbitrarily far into fStartPts (if loops gets big enough).

Original issue's description:
> Modify LineBench for drawing
>
> Currently we only have benchmark for lines that contains randomly generated
> points. This CL modifies the benchmark which adds cases of drawing straight
> lines. Also, this CL changes the call from drawPoints() to drawLines()
> which measures the performance of line drawing.
