Go patch committed: Fix names for types defined in functions

[Ian Lance Taylor]

This patch to the Go frontend fixes the names used for types defined in
functions.  Without this patch the names would use whatever appeared in
the -fgo-pkgpath or -fgo-prefix strings, which were not required to be
valid assembler identifier characters.  There is no need to use the
pkgpath/prefix string in the function name, because it will already
appear before the type name anyhow.  Bootstrapped and ran Go testsuite
on x86_64-unknown-linux-gnu.  Committed to mainline.
