Go patch committed: ignore function type result name in export data

[Ian Lance Taylor via Gcc-patches]

This patch to the Go frontend ignores the function type result name
when producing export data.  This change ensures that we never output
a result name in the export data if there is only a single result.
Previously we would output a ? if the single result had a name.  That
made the output unstable, because the hashing ignores the result name,
so whether we output a ? or not depended on how equal hash elements
were handled.  This is for GCC PR 104832.  Bootstrapped and ran Go
testsuite on x86_64-pc-linux-gnu.  Committed to mainline.
