[gccgo] More fixes for package prefixes

[Ian Lance Taylor]

Adding package prefixes required some more fixes when dealing with
type reflection and interface conversion.  This patch uses the package
prefix in hidden names, includes the package prefix in the hash code
for named types, and includes the package prefix in the pkg_path in
the type reflection structures.  This also fixes a crash when a
temporary variable has an erroneous type.  Committed to gccgo branch.
