add helper to create fancy underlines

Add a couple of utility functions to SkPaint that return the bounds
of glyphs between a pair of lines.

The common use case envisioned generates the edges of descenders
between the top and bottom bounds of an underline to allow computing
a stroke that skips those descenders.

The implementation stores a linked list in each glyph containing
the bounds of the lines parallel to the advance and the outermost
intersections within those bounds.

When the glyph cache is constructed, the glyph path is intersected
with the bounds and the extreme min and max values within the bounds
is added to an intercept.

Share the text to path iter to construct the data.

Make a half-hearted attempt to support vertical text; while the
vertical implementation is complete; surrounding code (e.g. paint
align) has short-comings with vertical.

sknx refactoring

  - trim unused specializations (Sk4i, Sk2d) and apis (SkNx_dup)
  - expand apis a little
    * v[0] == v.kth<0>()
    * SkNx_shuffle can now convert to different-sized vectors, e.g. Sk2f <-> Sk4f
  - remove anonymous namespace

I believe it's safe to remove the anonymous namespace right now.
We're worried about violating the One Definition Rule; the anonymous namespace protected us from that.

In Release builds, this is mostly moot, as everything tends to inline completely.
In Debug builds, violating the ODR is at worst an inconvenience, time spent trying to figure out why the bot is broken.

Now that we're building with SSE2/NEON everywhere, very few bots have even a chance about getting confused by two definitions of the same type or function.  Where we do compile variants depending on, e.g., SSSE3, we do so in static inline functions.  These are not subject to the ODR.

I plan to follow up with a tedious .kth<...>() -> [...] auto-replace.

This disables a few tests in DM:
   - one BlurLargeImage GM maybe is really broken
   - FontMgrAndroidParser uses libexpat, which I've not (yet?) built from source,
     so MSAN can't see into it.

This extends some of the MSAN stifling we added around SkImageDecoder_libjpeg to SkCodec, and skips .wbmps, .pngs, and .bmps.  We're only seeing issues in colortables for .png and .bmp.

I think I can probably back out disabling Codec and the RAW image decodes...
they should all be covered by the libjpeg stifles.

Add non-inline SkRTreeFactory constructor to fix clang-cl

When Chromium is switched to build with VS 2015 that switches clang-cl
to build in -fmsc-version=1900 mode. This causes some changes in
importing of constructors and vftables which leads to link errors in
blink_platform.dll. Adding a non-inline constructor makes 1900 mode
behave consistently with 1800 mode and avoids the link error.

The root cause needs investigation but this will unblock the VS 2015
switch.

Add Histogram Macros to Skia

Adds a set of histogram macros to Skia, modeled after Chrome's
UMA_HISTOGRAM_* macros. These allow logging of high frequency events,
and are useful to analyze real world usage of certain features.

By default, these macros are no-ops. Users can provide a custom
header file which defines these macros if they wish to collect
histogram data. Chrome will provide such a header.

I've currently only added two macros:
- SK_HISTOGRAM_BOOLEAN - logs a true/false type relationship (whether
we are tiling a texture or not on each draw).
- SK_HISTOGRAM_ENUMERATION - logs a set of potential values (which of
a number of choices were selected for the texture upload path).

We could add more unused macros at the moment, but it seems easier to
add these as needed, WDYT?
