compiler: avoid negative zero in float constants
Check for negative numbers with very small magnitudes that will round
to negative zero, and force 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.
Fixes golang/go#12621
