Pictures with many drawn paths benefit from the increase of the
count. As an example, chalkboard testcase has ~2500 paths, tiger
has ~300.
Bigger objects, like textures, tend to be limited by the cache
byte limit, not item count.

This changes SkScalarClampMax and SkScalarPin to use SkTMin and SkTMax.
This change allows compilers to more easily transform these operations
into fast max/min operarations as opposed to conditional branches.

When computed, the RTree for an SkPicture will have a root
bounds that reflects the best bounding information available,
rather than the best estimate at the time the picture recorder
is created. Given that creators frequently don't know ahead of
time what will be drawn, the RTree bound is often tighter.
Perf testing on Chrome indicates a small raster performance
advantage. For upcoming painting changes in Chrome the
performance advantage is much larger.

The tests assert on Sk_ColorGREEN, which is in BRGA non-premul. Read the
pixels in same color format.
Currently the tests pass on all platforms because GREEN is fully opaque
and the component stays in the same place both on BGRA and
RGBA. However, hypothetically somebody could copy-paste the assertion
for further tests but use, say, RED. This creates latent error that is
only visible on some platforms like mac.

Clamping 4 at a time is now about 15% faster than 1 at a time with SSSE3.
Clamping 4 at a time is now about 20% faster with SSE2,
and this applies to non-clamping too (we still just clamp there).
In all cases, 4 at a time is never worse than 1 at a time,
and not clamping is never slower than clamping.

The core of the problem is that the system is asked to lookup the metrics for a character with id == 0. This causes a hit in the fCharToGlyphHash matching the sentinel glyph. This happens because fCharToGlpyhHash is initialized with all zeros, therefore, the fID is zero matching the char with id == 0. The fAdvanceX field of the sentinel glyph is in fact not initialized.
The bigger question is now did a zero character get passed to getUnicharMetrics?
The breaking code is basically as follows:
wchar_t glyph = L'S';
paint.measureText(&glyph, 2);
This get mischaracterized as a utf8 string instead of a utf16(?) string. Because of the little endian ordering, this is the character string 'L' '\0'. Since the size of the original string is two bytes (but a single character) the '\0' is treated as its own character and past to getUnicharMetrics.
TEST:
On windows failed using DrMemory. With this change does not fail.

Please see if this looks usable. It may even give a perf boost if you use it, even without custom implementations for each instruction set.
I've been trying this morning to beat this naive loop implementation, but so far no luck with either _SSE2.h or _SSSE3.h. It's possible this is an artifact of the microbenchmark, because we're not doing anything between the conversions. I'd like to see how this fits into real code, what assembly's generated, what the hot spots are, etc.
I've updated the tests to test these new APIs, and splintered off a pair of new benchmarks that use the new APIs. This required some minor rejiggering in the benches.

Tasks that produce a non-fatal error will bail out before writing their output to
disk and hash to dm.json, but not count as failures.
This also makes true failures bail out before writing their results. If the DM
program failed, we probably don't want to triage that image result.
We use this new feature first to skip image subset decoding when we detect it's
not supported. Here's a snippet of an example run, where in this case only
.webp are subset decodable:
...
( 15MB 12) 172µs 8888 subset color_wheel.jpg (skipped: Subset decoding not supported.)
( 15MB 11) 9.05ms 8888 subset randPixels.webp
( 16MB 10) 863µs 8888 subset baby_tux.png (skipped: Subset decoding not supported.)
...
Only outputs corresponding to the .webp show up, both on disk and in the .json.
