Reason for revert:
UBSAN says we're reading a bad bool here:
bool usesDistanceVectorField() const { return fUsesDistanceVectorField; }
../../../include/gpu/GrPaint.h:83:51: runtime error: load of value 239, which is not a valid value for type 'bool'
SUMMARY: AddressSanitizer: undefined-behavior ../../../include/gpu/GrPaint.h:83:51 in
Seems likely also the root of Valgrind failure:

This update allows fragment processors to require a field of vectors to the nearest edge. This requirement propagates:
- from child FPs to their parent
- from parent FPs to the GrPaint
- from GrPaint through the PipelineBuilder into GrPipeline
- acessed from GrPipeline by GrGLSLProgramBuilder
GrGLSL generates a variable for the distance vector and passes it down to the GeometryProcessor->emitCode() method.
This CL's base is the CL for adding the BevelNormalSource API: https://codereview.chromium.org/2080993002

One side effect is that the SkShader's (or implicit shader's) fragment processor is responsible for the transition from an unpremul paint color to a premul color.

Added comment about how computeInvariantOutput() is non-recursive in GrFragmentProcessor
Made isEqual() recursive in GrFragmentProcessor

Fixed wrong indent
Changed auto child advance back to backwards linear search for getting subset of coords and samplers array of a child
Used offset from parent instead of backwards linear search to find a child proc's coords and transforms in Auto...Advance
append mangleString to variable name in nameVariable()
BUILDS! Added AutoFragmentChildProcAdvance class; fixed a few errors from previous commits

Changed childProcessor(i) to return const referencd
Fixed rootProc/parentProc offset issues; renamed a few things.
added nonempty check to gatherTransforms to avoid segfault
removed recursive append_gr_coord_transforms() from GrGLProgramBuilder
BUILDS! Changed num*includeProc() calls to num() calls
added gatherCoordTransforms(). added coordTransforms() for root proc only
Modified GrFragmentProcessor to append child proc transforms and textures to root proc's arrays.

Effectively all this does is future-proof any GLSL-specific code, as
GLSLCaps is just a typedef of GLCaps.

Since only XP's can read dst now, there is no reason to have this query on GrFP.
This also triggered a chain reaction of cleaning up/removing unnecessary code
elsewhere.
