Due to an oversight, libgo did not permit garbage collection to occur
on any compiler generated memory allocation.  It would only occur on
memory allocation in the runtime library, or when allocating memory
which was known to not hold pointers.  This libgo patch fixes that
oversight.  Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu.  Committed to mainline.
