6fe82e6b96 test/bench: note changes after recent improvements to locking and runtime 
Some tests are significantly faster (50%), a few are slower (up to 30%).
Fannkuch is confusing: parallel code is a little slower for gc, non-parallel and all gccgo runs are faster.

712fb6dcd3 os.Error API: don't export os.ErrorString, use os.NewError consistently 
This is a core API change.

1) gofix misc src
2) Manual adjustments to the following files under src/pkg:
   gob/decode.go
   rpc/client.go
   os/error.go
   io/io.go
   bufio/bufio.go
   http/request.go
   websocket/client.go
as well as:
   src/cmd/gofix/testdata/*.go.in (reverted)
   test/fixedbugs/bug243.go
3) Implemented gofix patch (oserrorstring.go) and test case (oserrorstring_test.go)

Compiles and runs all tests.

0b209b36b6 gc: relax assignability of method receivers 
The spec was adjusted in commit df410d6a4842 to allow the
implicit assignment of strutures with unexported fields in
method receivers.  This change updates the compiler.

Also moved bug322 into fixedbugs and updated golden.out
to reflect the removal of the last known bug.

Fixes #1402.

b6f0632e93 gc: correctly handle fields of pointer type to recursive forward references 
Previously, whether declaring a type which copied the structure of a type it was referenced in via a pointer field would work depended on whether you declared it before or after the type it copied, e.g. type T2 T1; type T1 struct { F *T2 } would work, however type T1 struct { F *T2 }; type T2 T1 wouldn't.
