This CL introduces a new path renderer.

Here are the characteristics :
- It uses the original path, before stroking
- It supports traight lines only (no curves)
- It supports butt or square caps only
- It supports miter or bevel joins only
- No AA support
Support for these will be added step by step later on.

A first pass at the benchmarks on my linux machine gave me these approximate speed improvements (running all bench with the option '--forceAA 0') :
path_stroke_small_long_line 4X
path_stroke_small_sawtooth 4X
path_stroke_big_rect 4X
path_stroke_small_rect 6X
path_stroke_big_triangle 4X
path_stroke_small_triangle 10X
lines_1_BW 1.5X
dashline_2_square 1.5X
dashline_1_square 1.5X

Also note that I can't submit this code until GrDrawTarget::isOpaque() is implemented, unless I just disable my renderer completely for now.

BUG=chromium:135111
TEST=The following gms are affected and may require rebaselining : lineclosepath, linepath, strokes_poly
