Go patch committed: Avoid crash on erroneous type

This patch to the Go frontend avoids crashing the compiler on an
erroneous type.  If there is an error constructing the backend type,
the GCC backend will report that the size is 1.  That will then cause
construction of the ptrmask to crash.  Avoid that case by just
generating an empty ptrmask.  Bootstrapped and ran Go testsuite on
x86_64-pc-linux-gnu.  Committed to mainline.

Ian
