classes from r3726 so they can be used. Does not implement any actual
effect stages.
Has one large known bug: if custom stages are provided, GrSamplerState
comparisons will break; this should preserve correct drawing, but decrease
performance - among other things, we'll break draw batching. To fix this
we'll need a RTTI system for GrCustomState objects, and we'll need to change
the GrSamplerState comparison from a memcmp to something that also does a
deep type-sensitive compare of any GrCustomState objects present.

Compact GrDrawState and nested structs; dynamically only copy and compare
the fields actually active on the structs in question.
Yields 10-20% speedup of text benchmarks in GPU configuration.
Could probably get additional marginal speedup by ignoring unused
kernel fields.
Has some fragile constructs: pointer math on members to compute
sizes of portions of structs.
Removes fields necessary for GrTesselatedPathRenderer.
