i965: Fix fragment shader struct inputs.

feature that have been passing for a long time.

Normally, varying packing splits up structures for us, so we don't see
them in the backend.  However, with SSO, varying packing isn't around
to save us, and we get actual structs that we have to handle.

This patch changes fs_visitor::emit_general_interpolation() to work
recursively, properly handling nested structs/arrays/and so on.
(It's easier to read with diff -b, as indentation changes.)

Ian Romanick [Tue, 3 Nov 2015 01:04:41 +0000 (17:04 -0800)]
i965: Don't pollute the buffer object namespace in brw_meta_fast_clear

tl;dr: For many types of GL object, we can *NEVER* use the Gen function.

In OpenGL ES (all versions!) and OpenGL compatibility profile,
applications don't have to call Gen functions.  The GL spec is very
clear about how you can mix-and-match generated names and non-generated
names: you can use any name you want for a particular object type until
you call the Gen function for that object type.

Here's the problem scenario:

 - Application calls a meta function that generates a name.  The first
   Gen will probably return 1.

 - Application decides to use the same name for an object of the same
   type without calling Gen.  Many demo programs use names 1, 2, 3,
   etc. without calling Gen.

 - Application calls the meta function again, and the meta function
   replaces the data.  The application's data is lost, and the app
   fails.  Have fun debugging that.

i965: Use internal functions for buffer object access

Instead of going through the GL API implementation functions, use the
lower-level functions.  This means that we have to keep track of a
pointer to the gl_buffer_object and the gl_vertex_array_object.

This has two advantages.  First, it avoids a bunch of CPU overhead in
looking up objects and validing API parameters.  Second, and much more
importantly, it will allow us to stop calling _mesa_GenBuffers /
_mesa_CreateBuffers and pollute the buffer namespace (next patch).

Revert "mesa: return initial value for VALIDATE_STATUS if pipe not bound"

This reverts commit ba02f7a3b6a0e4314753a8e5080db61241563f9c.

The commit checked whether the pipeline was currently bound instead
of checking whether it had ever been bound.  The previous setting
of Validated during object creation makes this unnecessary.  The
real problem was that Validated was not properly set to false
elsewhere in the code.  This is fixed by a later patch.

i965: Use NIR for lowering texture swizzle

Now that nir_lower_tex can do texture swizzle lowering, we can use that
instead of repeating more-or-less the same code in both backends.  This
both allows us to share code and means that things like the tg4

nir/validate: Validated dests after sources

Previously, if someone accidentally made an instruction that refers to its
own SSA destination, the validator wouldn't catch it.  The reason for this
is that it validated the destination too early and, by the time it got to
the source, the destination SSA value was already added to the set of seen
SSA values so it would assume that it came from some previous instruction.
By moving destination validation to be after source validation, the SSA
value is not in the list of seen values and the validator will catch
self-referential instructions.
