Part of this is a simple refactor, adapting any() and all() to the new
style of specialization.
And with that refactor in place, add AVX2/SSE4.1 for all() using ptest.
This isn't terribly important, but it does help make Op::asserts run
faster in the SkVM interpreter. I like to run with asserts enabled, and
this makes passing asserts much cheaper---failing asserts are expensive
still of course, printing to SkDebugf(), etc.

Turns out Clang's a lot better at auto-vectorizing "obvious" scalar code
into obvious vector code when it's written out the long way, e.g.
F32x4 x = ...;
x = { sqrtf(x[0]), sqrtf(x[1]), sqrtf(x[2]), sqrtf(x[3]) };
vectorizes into sqrtps a lot more reliably than our recurse-onto-scalars
strategy, and also better than the other naive approach,
F32x4 x = ...;
for (int i = 0; i < 4; i++) { x[i] = sqrtf(x[i]); }
So here I've added a map(V, fn) -> V' using C++14 tricks to let the
compiler handle the expansion of x = { fn(x[0]), fn(x[1]), ...
fn(x[N-1]) } for any N, and implemented most skvx scalar fallback code
using that.
With these now vectorizing well at any N, we can remove any
specializations we'd written for particular N, really tidying up.
Over in the SkVM interpreter, this is a big improvement for ceil and
floor, which were being done 2 floats at a time instead of 8. They're
now slimmed way down to
shlq $6, %r13
vroundps $K, (%r12,%r13), %ymm0
vroundps $K, 32(%r12,%r13), %ymm1
jmp ...
where K is 9 or 10 depending on the op.
I haven't found a scalar function that Clang will vectorize to vcvtps2pd
(the rounding one, not truncating vcvttps2pd), so I've kept lrint()
written the long way, updated to the style I've been using lately with
specializations inline.

Implement min and max using if_then_else(y<x,...) on vectors
rather than recursing to std::min/std::max applied to scalars.
But actually, factor out and use naive_if_then_else(), which Clang can
reason through better than it can our specialized if_then_else(). This
lets every min() or max() I've looked at compile down to ideal codegen,
vmaxps, vpminsw, etc, where if you use if_then_else() you'd see the
literal comparison and blend as written.
I've been looking at q14x2 codegen in the interpreter, and most things
were already good, unexpectedly even uavg_q14x2. The biggest surprise
was how bad the min/max codegen was, and looking back, even the min_f32
and max_f32 codegen is super bad. This CL fixes all that, leaving us
with the ideal codegen using the specific instruction you'd want,
replacing a giant mess of code that recursed down to scalars.
mul_q14x2 is still bad, but an easy follow up.
