This CL has a complicated back story, but it's concrete change is
simple, just turning the warning on and converting a bunch of
return foo;
to
return std::move(foo);
These changes are exclusively in places where RVO and NRVO do not apply,
so it should not conflict with warnings like -Wpessimizing-move.
Since C++11, when you return a named local and its type doesn't match
the declared return type exactly, there's an implicit std::move()
wrapped around the value (what I'm making explicit here) so the move
constructor gets an opportunity to take precedence over the copy
constructor. You can read about this implicit move here under the
section "automatic move from local variables and parameters":
https://en.cppreference.com/w/cpp/language/return#Notes.
This situation comes up for us with smart pointers: a function declares
its return type as std::unique_ptr<Base> or sk_sp<Base>, and we return a
std::unique_ptr<Impl> or sk_sp<Impl>. Those types don't match exactly,
so RVO and NRVO don't come into play. They've always been going through
move constructors, and that's not changed here, just made explicit.
There was apparently once a bug in the C++11 standard and compilers
implementing that which made these copy instead of move, and then this
sort of code would do a little unnecessary ref/unref dance for sk_sp,
and would entirely fail to compile for uncopyable std::unique_ptr.
These explicit moves ostensibly will make our code more compatible with
those older compilers.
That compatibility alone is, I think, a terrible reason to land this CL.
Like, actively bad. But... to balance that out, I think the explicit
std::move()s here actually help remind us that RVO/NRVO are not in play,
and remind us we're going to call the move constructor. So that C++11
standard bug becomes kind of useful for us, in that Clang added this
warning to catch it, and its fix improves readability.
So really read this all as, "warn about implicit std::move() on return".
In the end I think it's just about readability. I don't really hold any
hope out that we'll become compatible with those older compilers.

There is some logic in here for 2.0 as well, just as a
"as long as I was looking at the specs", but only 1.0
is really supported.
This seems to resolve the bug where some GPUs weren't
advertising correctly that they had vertex array object
support, by checking for both extension names (with and
without "GL_" prefix)
Of note, this saves about 18 Kb (5.5 Kb gzipped) of code size
by compiling out the unneeded GLES checks/functionality.

This CL creates a go program that takes a JSON file of
GPU functions and creates the assemble and validate code
based on that.
This approach will hopefully will lessen the need for
"shotgun surgery" anytime a new function/extensions is added.
Additionally, it should be easier to add a new standard
(concretely, WebGL) using this technique.
There are a few potential bugs/mismatches in the current
implementation that this has identified, for example,
Requiring GL 3.x for adding a feature, but only verifying
it is there on GL 4.x - I did not attempt to correct these
bugs in the old version, as we will hopefully be able to delete
that version and use the generated files.
