2015-10-06compiler: Record each import as a distinct alias.Ian Lance Taylor7-79/+129
This patch introduces the Package_alias class which is a finer representation of the different between a package and the aliases it is imported under. Each alias keeps track of the location of its import statement and how many times that alias has been used. This allows the gofrontend to report when a specific import has not been used even if a symbol from the package has been used by another import. Fixes golang/go#12326.
