The String method is called whenever the printing operation wants a string,
not just for %s and %v.

If there are no tags, the rules are the same as before.
If there is a tagged field, choose it if there is exactly one
at the top level of all fields.
More tests. The old tests were clearly inadequate, since
they all pass as is. The new tests only work with the new code.

The old code was incorrect and also broken. It passed the tests by accident.
The new algorithm is:
1) Sort the fields in order of names.
2) For all fields with the same name, sort in increasing depth.
3) Choose the single field with shortest depth.
If any of the fields of a given name has a tag, do the above using
tagged fields of that name only.

If the build key contains -race, the builder will invoke to the race.{bat,bash} build command. This allows {darwin,linux,windows}-amd64 builders to do race and non race builds in sequence.

cgo stores cgo LDFLAGS in _cgo_flags and _cgo_defun.c.
The _cgo_defun.c records the flags via
"#pragma cgo_ldflag <flag>", which external linking
relies upon for passing libraries (and search paths)
to the host linker.
The go command will allow LDFLAGS for cgo to be passed
through the environment (CGO_LDFLAGS); cgo ignores
this environment variable, and so its value doesn't
make it into the above mentioned files. This CL changes
cgo to record CGO_LDFLAGS also.
Fixes#5205.

The race detector uses a global lock to analyze atomic
operations. A panic in the middle of the code leaves the
lock acquired.
Similarly, the sync package may leave the race detectro
inconsistent when methods are called on nil pointers.

due to inferior pointers, reflect, gob, etc.
But this is essentially what I've used to debug
the GC issues.

Apologies for not reviewing the previous CL; I was on the road.
The text was misleading; execution is no more separate than with
any other test. Rewritten. Dropped the odd adverb.

The spec doesn't explicitly say that trailing data is okay, but a lot
of people do this and most unzippers will handle it just fine. In any
case, this makes the package more useful, and led me to make the
directory parsing code marginally more robust.

Don't measure wall time in map.go. Keep it portable
and only test NaN, but not time.
Move time tests to mapnan.go and only measure user CPU time,
not wall time. It builds on Darwin and Linux, the primary
platforms where people hack on the runtime & in particular
maps. The runtime is shared, though, so we don't need it to
run on all of the platforms.
