This should fix the Windows build, or at least
what's breaking it at the moment.
Fixes#5904.

This will behave like similar "*-other-window" functions in Emacs.
Default key bind is C-x 4 C-c C-j – while awkward, it follows both
the convention for other-window functions and the convention for
not using user- or emacs-reserved keys.

Update #543
I believe the runtime is strong enough now to reenable
preemption during the function prologue.
Assuming this is or can be made stable, it will be in Go 1.2.
More aggressive preemption is not planned for Go 1.2.

Currently preemption signal g->stackguard0==StackPreempt
can be lost if it is received when preemption is disabled
(e.g. m->lock!=0). This change duplicates the preemption
signal in g->preempt and restores g->stackguard0
when preemption is enabled.
Update #543.

With this CL, I believe the runtime always knows
the frame size during the gc walk. There is no fallback
to "assume entire stack frame of caller" anymore.

Add support for ECDHE-ECDSA (RFC4492), which uses an ephemeral server
key pair to perform ECDH with ECDSA signatures. Like ECDHE-RSA,
ECDHE-ECDSA also provides PFS.

clearfat (used to zero initialize structures) will use AX for x86 block ops. If we write to AX while calculating the dest pointer, we will fill the structure with incorrect values.
Since 64-bit arithmetic uses AX to synthesize a 64-bit register, getting an adress by indexing with 64-bit ops can clobber the register.

I have not done the system call stubs in sys_*.s.
I hope to avoid that, because those do not block, so those
frames will not appear in stack traces during garbage
collection.

While we're here, fix Syscall9 on NetBSD and OpenBSD:
it was storing the results into the wrong memory locations.
I guess no one uses that function's results on those systems.

Design at http://golang.org/s/go12symtab.
This enables some cleanup of the garbage collector metadata
that will be done in future CLs.
This CL does not move the old symtab and pclntab back into
an unmapped section of the file. That's a bit tricky and will be
done separately.

A type switch on a value with map index expressions,
could get a spurious instrumentation from a OTYPESW node.
These nodes do not need instrumentation because after
walk the type switch has been turned into a sequence
of ifs.

"M requires pointer receiver" can be misinterpreted to
mean that method M should have a pointer receiver but
does not. In fact the message means "M has a pointer
receiver" (and you don't have a pointer).

The postinstall script causes the installation to fail because the last
step that copies files for Xcode is broken. Two details can cause the
command to fail:
1. The XCODE_MISC_DIR value has a space. Without quotes in the cp
command, cp will just complain that this is an invalid syntax.
2. The source of the cp is a directory with two subdirectories.
We actually want the files for either Xcode 3 or Xcode 4 to be copied.
Using xcodebuild -version, we check for the Xcode version and
select which of xcode/3/* or xcode/4/* should be the source
of the copy.
