Update the Go library to the 1.10beta1 release.
Requires a few changes to the compiler for modifications to the map
runtime code, and to handle some nowritebarrier cases in the runtime.

gotools/:
* Makefile.am (go_cmd_vet_files): New variable.
(go_cmd_buildid_files, go_cmd_test2json_files): New variables.
(s-zdefaultcc): Change from constants to functions.
(noinst_PROGRAMS): Add vet, buildid, and test2json.
(cgo$(EXEEXT)): Link against $(LIBGOTOOL).
(vet$(EXEEXT)): New target.
(buildid$(EXEEXT)): New target.
(test2json$(EXEEXT)): New target.
(install-exec-local): Install all $(noinst_PROGRAMS).
(uninstall-local): Uninstasll all $(noinst_PROGRAMS).
(check-go-tool): Depend on $(noinst_PROGRAMS). Copy down
objabi.go.
(check-runtime): Depend on $(noinst_PROGRAMS).
(check-cgo-test, check-carchive-test): Likewise.
(check-vet): New target.
(check): Depend on check-vet. Look at cmd_vet-testlog.
(.PHONY): Add check-vet.
* Makefile.in: Rebuild.
