Authentication-results: sourceware.org; auth=none

This patch to the Go frontend checks for negative numbers with very
small magnitudes that will round to negative zero, and forces them to
positive zero instead.  This implements the spec clarification in
https://golang.org/cl/14727.  The test is in
https://golang.org/cl/91895.  This fixes golang.org/issue/12621.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.

Ian
