Cherry-pick: cc: Always perform analysis to detect solid color tiles.

Clean cherry-pick of chromium

BUG: 16133204

Original description:

One previous approach was to try and balance memory usage vs amount
of time we spend analyzing tiles. This patch switches it so that we
always analyze tiles in order to try and save as much memory as

This is due to the fact that there are some cases out there that
break the heuristic and use too much memory, when otherwise they
would be detected as solid.

As well, it enables analysis for gpu rasterization since it also
needs to start benefitting from these memory savings.
