DIVBITS_ITER was shifting bits up into the sign bit, which is a no-no.
This turns numer into a uint32_t to make those defined, and adds a few notes.
x >= 0 is always true for unsigned x, so we needed a few small logic refactors.

The general SkImage features seem to be tested in
ImageTest instead of SurfaceTest.
Helps in reviewing further reformatting of SurfaceTest.

_mm_mulhi_epu16 makes the (...*257)>>16 part simple.
This seems to speed up every transfermode that uses div255(),
in the 7-25% range.
It even appears to obviate the need for approxMulDiv255() on SSE.
I'm not sure about NEON yet, so I'll keep approxMulDiv255() for now.
Should be no pixels change:

- extract alpha from a pixel: 5 1-cycle ops to 4 1-cycle ops
- load alphas: drop 4 unnecessary ops
Should be no pixel diffs.

Extend the SkPath API to allow specifying the contour starting point.
This will allow removing the explicit cubic code from Blink/Path.

- streamline the testing down to just byte multiplies
(that's always where the blend algorithms vary)
- add another approximate multiply (x*y+255)>>8
- add another variant of the perfect multiply, ((x*y+128)*257)>>16
I've realized ((x*y+128)*257)>>16 might be just as fast in SSE/NEON
as our current (x*y+x)>>8 approximation. Good to be testing it here.

testcase7.bmp leaves uninitialized memory.
Also remove "subset" dm flags. The "subset" test no longer
exists.

This makes it match OS X build more closely.
The most important change is that CLANG_CXX_LIBRARY sets -stdlib=libc++
for both the compiler and the linker.

This a safety check to ensure that we don't accidentally ship subset
decoders for non-required formats.

This shouldn't really make any difference but allocating and holding on to a GrRenderTarget for each test target generates image differences for Mali GPUs. This CL allows an existing render target to be used for the test target.

* /user/download: remove instruction to compile and run skia
tests - moved to /user/quick/${OS}
* /user/quick/desktop: move Gyp options to a section in the
FAQ (distracts from quick start narritive).
* /user/tips: reformat, rewrite.

This CL:
Fixes an ordering problem w.r.t. drawTarget clean up in GrContext::abandonContext (for text test that abandons context)
Fixes when the lastDrawTarget field is set on a RenderTarget (now in GrDrawTarget ctor) due to GrTestTarget use case
Updates the ProgramUnitTest to use multiple drawTargets
Adds renderTarget creation to GrTestTargets (in MDB drawTargets require them)

Reason for revert:
Speculative revert for leaks based on ASAN bot (and some local valgrind testing)
