If named types with similar names are defined inside of methods
with similar names, it was possible that the mangled type names would be
the same, leading to multiple definitions of type descriptor and
garbage collection info variables.
This can only occur with similarly named methods across different
receivers, so we use the receiver name to distinguish.

Fixes issue 33.

With my last change, `sed' is used to cut out the target name from a listed
target. Since there may be additional OPTions encoded in the "target", I tried
to get only the first submatch before an `OPT'. However, `sed' uses longest
match, so I'm re-writing this using awk.

  If anybody is like using `gawk' or anything different, please feel free to
drop another patch. Since this is usually called by hand or by robots under
review, I don't see much of a problem here.
