Speed up GrDrawState handling.
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.
