These are basically inlined, 4-at-a-time versions of our existing functions,
but cut down to avoid any work that's only necessary outside [0,1].
Both f16 and f32 denorms should work fine modulo the usual ARMv7 NEON denorm==zero caveat.
In exchange for a little speed, f32->f16 does not round properly.
Instead it truncates, so it's never off by more than 1 bit.
Support for finite values >1 or <0 is straightforward to add back.

Remove reference to SkImageDecoder from SkPicture. Make the default
InstallPixelRefProc passed to CreateFromStream use
SkImageGenerator::NewFromEncoded instead.
Make SkImageGenerator::NewFromEncoded create an SkCodecImageGenerator.
Remove the old version that used SkImageDecoder.
Remove all versions of lazy_decode_bitmap/LazyDecodeBitmap. The default
now behaves lazily.
Update all clients to use the default.
Move SkImageDecoderGenerator into KtxTest.cpp, and use it directly.

The use of SkNEW_APPEND_TO_TARRAY is now better served by
SkTArray::emplace_back(...) which should now be used instead. The
existing users of SkNEW_APPEND_TO_TARRAY are converted and the code
relating to SkNEW_APPEND_TO_TARRAY is removed.
TBR=reed
This only removes code. The file should also be made private.

- 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 is a synonym for the version of getAndroidPixels that accepts
only three parameters (i.e. no AndroidOptions). It is very similar
to SkCodec::getPixels, so I think the motivation for naming the
version with options differently does not apply here.
Add comments to the header describing defaults.
Update the test to use a template, and delete a lot of redundant code.
Rename a variable to stop shadowing another variable.

If a client requests unpremul or premul from an opaque SkCodec,
support it. The opaque image can be treated as any of them, though
it will be less efficient to draw than if the client had used
opaque.
Change the filling code (i.e. for incomplete images) to base its color on
the source alpha type. Prior to adding the support to decode opaque to
any, it was fine to use either source or dest (which would have yielded
the same result). If the client requests non-opaque, we do not want this
to switch the fill value from black to transparent. This also allows
simplifying the signatures for getFillValue and onGetFillValue.
In CodexTest, expect the same result when decoding opaque to *premul,
and compare to the opaque version.
