The cmd/compile/internal/ssa/gen directory can't depend on cmd/internal/gc
because that package doesn't exist in go1.4. Use strings instead of
constants from that package.
The asm fields seem somewhat redundant to the opcode names we
conventionally use. Maybe we can just trim the lowercase from the end
of the op name? At least by default?

Add an asm field to opcodeTable containing the Prog's as field.
Then instructions that fill the Prog the same way can be collapsed
into a single switch case.
I'm still thinking of a better way to reduce redundancy, but
I think this might be a good temporary solution to prevent duplication
from getting out of control. What do you think?

Add an additional int64 auxiliary field to Value.
There are two main reasons for doing this:
1) Ints in interfaces require allocation, and we store ints in Aux a lot.
2) I'd like to have both *gc.Sym and int offsets included in lots
of operations (e.g. MOVQloadidx8). It will be more efficient to
store them as separate fields instead of a pointer to a sym/int pair.
It also simplifies a bunch of code.
This is just the refactoring. I'll start using this some more in a
subsequent changelist.

Process.handle was accessed without synchronization while wait() and
signal() could be called concurrently.
A first solution was to add a Mutex in Process but it was probably too
invasive given Process.handle is only used on Windows.
This version uses atomic operations to read the handle value. There is
still a race between isDone() and the value of the handle, but it only
leads to slightly incorrect error codes. The caller may get a:
errors.New("os: process already finished")
instead of:
syscall.EINVAL
which sounds harmless.

Previously we enforced both that the extended key usages of a client
certificate chain allowed for client authentication, and that the
client-auth EKU was in the leaf certificate.
This change removes the latter requirement. It's still the case that the
chain must be compatible with the client-auth EKU (i.e. that a parent
certificate isn't limited to another usage, like S/MIME), but we'll now
accept a leaf certificate with no EKUs for client-auth.
While it would be nice if all client certificates were explicit in their
intended purpose, I no longer feel that this battle is worthwhile.

The documentation for quick.Value says that it "returns an arbitrary
value of the given type." In spite of this, nil values for pointers were
never generated, which seems more like an oversight than an intentional
choice.
The lack of nil values meant that testing recursive type like
type Node struct {
Next *Node
}
with testing/quick would lead to a stack overflow since the data
structure would never terminate.
This change may break tests that don't check for nil with pointers
returned from quick.Value. Two such instances were found in the standard
library, one of which was in the testing/quick package itself.
