cmd/gc: shorten name used for map bucket type
Before:
type.struct { buckets *struct { overflow *struct { overflow *struct { overflow *struct { overflow *struct { overflow *<...>; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; oldbuckets *struct { overflow *struct { overflow *struct { overflow *struct { overflow *struct { overflow *<...>; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable } }
After:
type.map.bucket[string]*"".RangeTable
This makes debugging maps a little nicer, and it takes up less space in the binary.
