Re-apply @adg's CL https://golang.org/cl/7129048 that was
previously disabled in https://golang.org/cl/7235052 because
it broke `godoc net/http` for go1.1.

Currently `godoc net/http` seems to work fine with this CL.

Fixes #3428.

Trace viewer cannot handle traces larger than 256MB (limit on js string size):
https://github.com/catapult-project/catapult/issues/627
And even that is problematic (chrome hangs and crashes).
Split large traces into 100MB parts. Somewhat clumsy, but I don't see any other
solution (other than rewriting trace viewer). At least it works reliably now.

This is addressing feedback given on golang.org/cl/23052;
we do it in a separate CL to separate the functional from
the rename change.

ONAME was not used in the export data, but it's the natural node op
where we used OPACK instead. Renamed.

Furthermore, OPACK and ONONAME nodes are replaced by the type checker
with ONAME nodes, so OPACK nodes cannot occur when exporting type-checked
code. Removed a special-case for OPACK nodes since they don't appear.

The -systemdll and -xsys flags generate broken code in some situations
(see issue for details). Fix all that.

This CL only fixes bugs in existing code, but I have more changes comming:

golang.org/x/sys/windows is not the only package that uses mksyscall_windows.go.
golang.org/x/exp/shiny and github.com/derekparker/delve do too. I also have
few personal packages that use mksyscall_windows.go. None of those packages
are aware of new -xsys flag. I would like to change mksyscall_windows.go, so
external packages do not need to use -xsys flag. I would love to get rid of
-xsys flag altogether, but I don't see how it is possible. So I will, probably,
replace -xsys with a flag that means opposite to -xsys, and use new flag
everywhere in standard libraries. Flag name suggestions are welcome.

-systemdll flag makes users code more "secure". I would like to make -systemdll
behaviour a default for all mksyscall_windows.go users. We use that already in
standard library. If we think "secure" is important, we should encourage it in
all users code. If mksyscall_windows.go user insist on using old code, provide
-use_old_loaddll (need good name here) flag for that. So -systemdll flag will
be replaced with -use_old_loaddll.

This change makes encoding and decoding support integer types in map
keys, converting to/from JSON string keys.

JSON object keys are still sorted lexically, even though the keys may be
integer strings.

For backwards-compatibility, the existing Text(Un)Marshaler support for
map keys (added in CL 20356) does not take precedence over the default
encoding for string types. There is no such concern for integer types,
so integer map key encoding is only used as a fallback if the map key
type is not a Text(Un)Marshaler.

The time package has never depended on the io package until
a recent change during Go 1.7 to use the io.Seek* constants.

The go/build dependency check didn't catch this because "time" was
allowed to depend on meta package group "L0", which included "io".

Adding the "io" package broke one of Dmitry's tools. The tool is
fixable, but it's also not necessary for us to depend on "io" at all
for some constants. Mirror the constants instead, and change
deps_test.go to prevent an io dependency in the future.
