If the analysis reached a node twice, then the analysis was cut off.
However, if the second arrival is at a lower depth (closer to escaping)
then it is important to repeat the traversal.

The repeating must be cut off at some point to avoid the occasional
infinite recursion. This CL cuts it off as soon as possible while still
passing all tests.

Fixes #4751.

This CL adds TCPInfo struct to linux/386,arm.
It's already added to linux/amd64.

Note that not sure the reason but cgo godefs w/ latest gcc
translates a flexible array member in structures correctly,
handles it as a non-incomplete, non-opaque type, on Go 1.
This CL reverts such changes by hand for the Go 1 contract.

Was not re-walking the new AND node, so that its ullman
count was wrong, so that the code generator attempted to
store values in registers across the call.

In cmd/go's 'go help testflag':
* Rewrite list of flags to drop test. prefix on every name.
* Sort list of flags.
* Add example of using -bench to match all benchmarks.

In testing:
* Remove mention of undefined 'CPU group' concept.

* Document Parse's zone interpretation.
* Add ParseInLocation (API change).
* Recognize "wrong" time zone names, like daylight savings time in winter.
* Disambiguate time zone names using offset (like winter EST vs summer EST in Sydney).

The final two are backwards-incompatible changes, but I believe
they are both buggy behavior in the Go 1.0 versions; the old results
were more wrong than the new ones.

Fixes #3604.
Fixes #3653.
Fixes #4001.

* Avoid treating CALL fn(SB) as justification for introducing
and tracking a registerized variable for fn(SB).

* Remove USED(n) after declaration and zeroing of n.
It was left over from when the compiler emitted more
aggressive set and not used errors, and it was keeping
the optimizer from removing a redundant zeroing of n
when n was a pointer or integer variable.

For consistency with conversions that look like function calls,
conversions that don't look like function calls now allow an
optional trailing comma.

That is, int(x,) has always been syntactically valid.
Now []int(x,) is valid too.
