This fixes a regression that was made when adding
support for building with gccgo (in d6a14e6fac0c).

External commands (those not from the Go tree) were
being installed to the package directory instead of
the binary directory.

yacc is also fixed (it was wrong before)
All that's left is the commands used during compilation
This looks like a huge CL, but it's almost all file renames.

1) create go-tool dir in make.bash
2) clean up stale binaries in make.bash
3) add 'tool' command to go
4) convert goyacc->yacc as a first test tool
Since goyacc stands alone, it's a safe trial.

Added flag AllMethods: if not set (future default), embedded
methods of exported (and thus visible) embedded fields are not
shown in the final package documentation

The actual change for AllMethods is just in sortedFuncs. All
other changes are simplifications of the existing logic (mostly
deletion of code): Because method conflicts due to embedding
must always be detected, remove any premature elimination of
types and methods. Instead collect all named types and all
methods and do the filtering at the end.

Miscellaneous:
- renamed baseType -> namedType
- streamline logic for recording embedded types
- record embedded types via a map (simpler data structures)

AllMethods is set by default; so the output is unchanged and
the tests pass. The next CL will enable the AllMethods flag
and have adjusted tests (and fix issue 2791).

The use of gccgo is triggered by GC=gccgo in environment. It
still needs the standard distribution to behave properly, but
allows using the test, build, run, install subcommands with
gccgo.
