could not resist: fast sse float <--> u16
...
- generalizes the bench to float <--> {u8,u16}
- must remember to implement NEON version at some point

SkNx Load/store: take any pointer.
...
This means we can remove a lot of explicit casts in code that uses SkNx.

Unify some SkNx code
...
- one base case and one N=1 case instead of two each (or three with doubles)
- use SkNx_cast instead of FromBytes/toBytes
- 4-at-a-time Sk4f::ToBytes becomes a special standalone Sk4f_ToBytes
If I did everything right, this'll be perf- and pixel- neutral.

Add Sk4f::ToBytes(uint8_t[16], Sk4f, Sk4f, Sk4f, Sk4f)
...
This is a big speedup for float -> byte. E.g. gradient_linear_clamp_3color:
x86-64 147µs -> 103µs (Broadwell MBP)
arm64 2.03ms -> 648µs (Galaxy S6)
armv7 1.12ms -> 489µs (Galaxy S6, same device!)

Remove const from const int loops.
...
This drives me nuts, and prevents `while (loops --> 0)`.

Clean up remaining users of SkPMFloat
...
This switches over SkXfermodes_opts.h and SkColorMatrixFilter to use Sk4f,
and converts the SkPMFloat benches to Sk4f benches.
No pixels should change here, and no code beyond the Sk4f_ benches should change speed.
The benches are faster than the old versions.
