Compile time vertex layout masks

This is me waiving a white flag.

code is fine, but I'm not sure I could regenerate those tables

http://codereview.appspot.com/5493049/diff/1/src/gpu/GrDrawTarget.cpp
File src/gpu/GrDrawTarget.cpp (right):

http://codereview.appspot.com/5493049/diff/1/src/gpu/GrDrawTarget.cpp#newcode46
src/gpu/GrDrawTarget.cpp:46: /* These values were generated by the above
function */
can you show exactly how one would call gen_mask_arrays to re-generate these
values? e.g.

#if 0
static void rebuild_stage_arrays() {
    ...
     gen_mask_arrays(...);
     for ...
        printf("gStageTexCoordMasks[] = { %d %d %d ...);
}

Done. I added a function that prints the decl/init code.
