mtklein 3faf74b836 skcpu: sse4.1 floor, f16c f16<->f32 
-  floor with roundps is about 4.5x faster when available
  -  f16 srcover_n is similar to but a little faster than the version in https://codereview.chromium.org/1884683002.  This new one fuses the dst load/stores into the f16<->f32 conversions:

+0x180	    movups              (%r15), %xmm1
+0x184	    vcvtph2ps           (%rbx), %xmm2
+0x189	    movaps              %xmm1, %xmm3
+0x18c	    shufps              $255, %xmm3, %xmm3
+0x190	    movaps              %xmm0, %xmm4
+0x193	    subps               %xmm3, %xmm4
+0x196	    mulps               %xmm2, %xmm4
+0x199	    addps               %xmm1, %xmm4
+0x19c	    vcvtps2ph           $0, %xmm4, (%rbx)
+0x1a2	    addq                $16, %r15
+0x1a6	    addq                $8, %rbx
+0x1aa	    decl                %r14d
+0x1ad	    jne                 +0x180

If we decide to land this it'd be a good idea to convert most or all users of SkFloatToHalf_01 and SkHalfToFloat_01 over to the pointer-based versions.
