Put all XSAN bots on the same DEPS-sourced build of Clang.

This adds LLVM, Clang, and compiler-rt (*san tools) to DEPS,
then uses them from xsan_build, building them if needed.

This is similar to how the CMake bots bootstrap CMake if needed.

Use noperspective interpolation for 2D draws

Adds a mechanism to notify GrGLSLVaryingHandler that a shader will not
emit geometry in perspective. This gives it a chance to use the
noperspective keyword if it is supported.

Updates the existing processors to notify the varying handler when
there is no perspective.

Begins using the noperspective keyword in GrGLGpu internal shaders.

Web scenes with observable benefit (Pixel C, gpu config):

  tabl_nofolo.skp        4.62 -> 3.33 ms   28%
  desk_tigersvg.skp      26.5 -> 24 ms      9%
  desk_pokemonwiki.skp   16.1 -> 14.9 ms    7%
  tabl_deviantart.skp    3.97 -> 3.7 ms     7%
  desk_gws.skp           3.85 -> 3.65 ms    5%

Also adds new methods for creating varyings with flat interpolation.

SkNx refactoring

  - add back Sk4i typedef

      * uint16 <-> float becomes uint16 <-> int <-> float

    This has the nice side effect of specializing uint8 <-> int
    and uint16 <-> int, which are useful in their own right.

There are many cast specializations now, some of which call each other.
I have tried to arrange them in some sort of sensible order, subject to
the constraint that those called must precede those who call.
