Yes, please. The more we can do at link time the better. |

image/color/palette appears to be a good test case for this in the stdlib. |

When possible, emit static data rather than init functions for interface values. This: * cuts 32k off cmd/go * removes several error values from runtime init * cuts the size of thenimage/color/palette compiled package from 103k to 34k * reduces the time to build the package in golang#15520 from 8s to 1.5s Fixes golang#15528 Change-Id: I317112da17aadb180c958ea328ab380f83e640b4

CL prepared for 1.8. Unstable url for those who want to peek. |

The code in #15520 generates a giant init function, aimed at setting up an array of interface values. The components are, however, entirely static: Static itab and static data. We should thus be able to create the entire array statically instead of making an init function.
