In Python 3, iteration order over the contents of a native `dict` is always unpredictable, which results in bugs like bug 1635755 where `xptdata.cpp` has irreproducible content. To avoid this, we be sure to always write out JSON in a fixed, deterministic order.

GENERATED_FILES now defaults to python3 unless py2=True is specified as
an argument. All existing GENERATED_FILES scripts and GeneratedFile
templates have the py2=True attribute added, so this patch should
effectively be a no-op.
Going forward, individual scripts can be converted to python3 and their
corresponding py2=True attribute can be deleted. In effect, this patch
will be backed out in pieces until all scripts run in python3, at which
point the py2 attribute itself can be removed.

Fix handling of ABI arguments in xptcinvoke for PPC64 platforms. Previously, non-floating-point arguments would advance the index of which floating-point register to use. This cleans up both of the platform-specific invoke and stubs to be better aligned to the x86_64 model.

This contains two changes. One is to zero out the top 56 bits for a bool
conversion so we can pass bools correctly from cpp -> js. This was also
needed in Bug 821628, 1513725
The other change copies the fix in Bug 689288 where we cast a float value
as a double.

When we're lowering extra types (e.g. array element types) and we find
that we haven't already lowered the type, we say that the new type is
going to live at the end of the `types` array. But we don't append a
new type (i.e. filling in the entry) until after we call `lower_type`,
which means that some other call to `lower_extra_type` might find
that *its* new type will live at the same position we "allocated" higher
up on the stack.
We don't appear to run into this issue, as the only nested array types
are things like `Array<Array<uint8>>`, and `uint8` is guaranteed to
already have been lowered. But if people start doing more complicated
things, we're bound to run into this sooner or later.

XPCConvert::IsMethodReflectable() is derived entirely from
nsXPTMethodInfo, so we can compute it at build time and include it in
nsXPTMethodInfo. It is the only use of mNotXPCOM and mHidden, so we
can get rid of those fields at the same time.
This paves the way for getting rid of XPCWrappedJSClass::mDescriptors
in the next patch.

ARM's xptcstubs use a slightly different setup for PrepareAndDispatch
than...well, all of our other stubs. This difference appears to be
causing problems with LTO builds. Change the setup to be more like our
other stubs, which additionally gets rid of some of the `asm` nonsense.

Currently the [ref] and [ptr] types share the same underlying
implementation. This is unfortunate, and can cause correctness problems
with outparam refs (as an example).
By using the same tools used to allow other larger objects (such as
jsid, nsTArray, and nsString) to be stored directly in the nsXPTCVariant
object, this patch directly stores the nsID in the nsXPTCVariant object
when calling from JS into C++.
Using this new strategy avoids an nsID* allocation every time we pass
one over XPConnect, and should also allow us to simplify callers.
In addition, some special casing is added to xpidl to make it possible
to use the nsid reference type objects directly inside of Array<T>,
which will allow us to remove `[array] nsIIDPtr` callers.

The basic idea for the changes around UnwrapObjectInternal and its callers
(UnwrapObject, UNWRAP_OBJECT, etc) is to add a parameter to the guts of the
object-unwrapping code in bindings which can be either a JSContext* or nullptr
(statically typed). Then we test which type it is and do either a
CheckedUnwrapDynamic or CheckedUnwrapStatic. Since the type is known at
compile time, there is no actual runtime check; the compiler just emits a call
to the right thing directly (verified by examining the assembly output on
Linux).
The rest of the changes are mostly propagating through that template parameter,
adding static asserts to make sure people don't accidentally pass nullptr while
trying to unwrap to a type that might be a WindowProxy or Location, etc.
There are also some changes to places that were calling CheckedUnwrap directly
to use either the static or dynamic version, as needed.
