Add SSE, SSE4.1, and NEON specializations.
The if_then_else() unit tests in SkVxTest.cpp should cover this.
I had to give up on my dream of not using Skia headers for now. There's
really no good way of knowing whether we've got SSE4.1 support in MSVC
except when we explicitly define SK_CPU_SSE_LEVEL=SK_CPU_SSE_LEVEL_SSE41.
This refactor to use SK_CPU_SSE_LEVEL let MSVC point out a slight
ordering problem that would cause an infinite loop calling any of
the specializions like sqrt(float2). I believe moving them after
the float4 specializations will fix that.

- remove ALWAYS_INLINE until we find we need it
- make bit_puns explicit
- implement everything recursively so, e.g.
sqrt(float8) picks up sqrt(float4) when
not otherwise specialized.
- implement SSE specializations:
of the operations I tested, only sqrt, rcp, and rsqrt
needed any help. The others look good as-is.

Obviously lots of these new operations like sqrt() will want platform
specialization. That'll come later.
