This patch to the GCC 5 branch fixes PR 65755. This is a conservative patch for the branch. I will shortly apply a more complete, less conservative, patch to trunk. This patch simply adds the receiver type when producing the pkgpath or the reflection string for a type defined within a method. It also emits the pkgpath in the reflection string even when not using the -fgo-pkgpath option. For this patch bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
