mtklein ed814f34c7 Revert of de-proc sk_float_rsqrt (patchset #3 id:40001 of https://codereview.chromium.org/1616013003/ ) 
Reason for revert:
This is somehow blocking the Google3 roll in ways neither Ben nor I understand.  Precautionary revert... will try again Monday.

Original issue's description:
> de-proc sk_float_rsqrt
