Brian Salomon d8d85b9b89 Reland "Don't key progams/pipelines on origin."" 
Reland works around Adreno issue with this formulation of sk_Clockwise:
 (sk_RTFlip.y < 0.0 ? !gl_FrontFacing : gl_FrontFacing)

and instead adds this to the top of the function:
 bool sk_Clockwise = gl_FrontFacing;
 if (sk_RTFlip.y < 0.0) {
      sk_Clockwise = !sk_Clockwise;
 }

Original description:

SkSL language features that are origin sensitive now use a uniform
to conditionally flip their result rather than generating different
code.

Previously we would insert a "rt height" uniform if sk_FragCoord needed
to be flipped. sk_FragCoord,y was implemented as "realFragCoord.y" or
"rtHeight - realFragCoord.y" depending on SkSL::ProgramSettings::fFlipY.

Now we instead use a two component vector rtFlip and sk_FragCoord.y is
always "rtFlip.x + rtFlip.y*realFragCoord.y". We configure rtFlip as
either (0, 1) or (rtHeight, -1). sk_Clockwise and dFdy simiarly use
rtFlip.y to emit code that always works with either origin.
