In cl/8652 I broke darwin/arm and darwin/386 because I removed the *g
parameter, which they both expect and use. This CL adjusts both ports
to look for g0 in m, just as darwin/amd64 does.
Tested on darwin{386,arm,amd64}.

This is a practice run for darwin/arm.
Similar to the linux/amd64 shared library entry point. With several
pending linker changes I am successfully using this to implement
-buildmode=c-archive on darwin/amd64 with external linking.
The same entry point can be reused to implement -buildmode=c-shared
on darwin/amd64, however that will require further ld changes to
remove all text relocations.
One extra runtime change will follow this. According to the Go
execution modes document, -buildmode=c-archive should ignore the Go
main function. Right now it is being executed (and the process exits
if it doesn't block). I'm still searching for the right way to do
this.

The linker currently (on some platforms) takes a -shared flag, which means
approximately what -buildmode=c-shared means in the in the proposed "Go
Execution Modes" document. As part of implementing other modes, the term
"shared" becomes horribly overloaded, so this replaces -shared with a
-buildmode argument instead (which currently only handles -buildmode=c-shared
and the default -buildmode=exe -- no new behaviour here).
As the linker support for -shared was in 1.4 this retains it as an alias.

This CL is quite conservative in some ways. It continues to define
symbols that have no real purpose (e.g. epclntab). These could be
deleted if there is no concern that external tools might look for them.
It would also now be possible to make some changes to the pcln data but
I get the impression that would definitely require some thought and
discussion.

Previously if the connection pool was larger than maxBadConnRetries
and there were a lot of bad connections in the pool (for example if
the database server was restarted), a query might have failed with an
ErrBadConn unnecessarily. Instead of trying to guess how many times
to retry, try maxBadConnRetries times and then force a fresh
connection to be used for the last attempt. At the same time, lower
maxBadConnRetries to a smaller value now that it's not that important
to retry so many times from the free connection list.

This is a first step towards moving go/types from the tools
repo into the std repo. The files were brought over via the
added src/go/types.bash script for reproducability. The
script can be removed once all dependencies on go/types
have moved to the std repo go/types.
The script moved packages as follows:
- x/tools/go/types => go/types (type-checker)
- x/tools/go/exact => go/exact (constants)
- x/tools/go/gcimporter => go/types/internal/gcimporter
The gcimporter is needed to be able to run tests. go/types
should probably have some factory function to provide an
appropriate importer.
Some of the go/types tests fail for a handful of platforms
(windows and nacl). In order to keep this change "clean"
from manual changes, the next change will disable those
tests for now so we can move forward.
