commit-bot@chromium.org 73fffeb83a Add pattern matchers for SkRecord 
This is a mid-level library for finding patterns of commands in an SkRecord.  At the API level, it's a bit regex inspired.  Some examples:
 - Pattern1<Is<DrawRect>> matches a single DrawRect

 - Pattern1<Star<Is<DrawRect>>> matches 0 or more DrawRects

 - Pattern2<Is<ClipRect>, Is<DrawRect>> matches a single clip rect followed by a single draw rect

  - Pattern3<Is<Save>, Star<IsDraw>, Is<Restore>> matches a single Save, followed by any number of Draws, followed by Restore

 - Pattern1<Or<Is<DrawRect>, Is<ClipRect>>> matches a DrawRect or a ClipRect

 - Pattern1<Not<Is<ClipRect>>> matches a command that's notClipRect.

Once you have a pattern, you can call .search() on it to step through ranges of matching commands.  This means patterns can replace most of the custom iteration logic for optimization passes: the generic pattern searching steps through all the optimization candidates, which optimization-specific code further inspects and mutates.

SkRecordTraits is now unused.  Bye bye!

Generated code and performance of SkRecordOpts is very similar to what it was before.  (I had to use SK_ALWAYS_INLINE in a few places to make this so.)
