The nir_state_slot struct had some padding that was never initialized.
Serializing the individual parts of the struct is more robust and avoids
the overhead of zeroing it at creation, so just do that.

From the ARB_enhanced_layouts specification:
"For the property TRANSFORM_FEEDBACK_BUFFER_INDEX, a single integer
identifying the index of the active transform feedback buffer
associated with an active variable is written to <params>. For
variables corresponding to the special names "gl_NextBuffer",
"gl_SkipComponents1", "gl_SkipComponents2", "gl_SkipComponents3",
and "gl_SkipComponents4", -1 is written to <params>."
We were storing the xfb_buffer value, instead of the value
corresponding to GL_TRANSFORM_FEEDBACK_BUFFER_INDEX.
Note that the implementation assumes that varyings would be sorted by
offset and buffer.

On OpenGL, a array of a simple type adds just one varying. So
gl_transform_feedback_varying_info struct defined at mtypes.h includes
the parameters Type (base_type) and Size (number of elements).
This commit checks this when the recursive add_var_xfb_outputs call
handles arrays, to ensure that just one is addded.

Right now we are only re-sorting outputs. But it is better to sort too
varyings, as linker expect them to be sorted out (as it was done on
GLSL). For varyings, and to make easier to compute buffer_index, we
sort also by buffer. We could do the same for outputs, but we lack a
reason for that, so we left it as it is (just offset).

In order to be used for OpenGL (right now for ARB_gl_spirv).
This commit adds two new structures:
* nir_xfb_varying_info: that identifies each individual varying. For
each one, we need to know the type, buffer and xfb_offset
* nir_xfb_buffer_info: as now for each buffer, in addition to the
stride, we need to know how many varyings are assigned to it.
For this patch, the only case where num_outputs != num_varyings is
with the case of doubles, that for dvec3/4 could require more than one
output. There are more cases though (like aoa), that will be handled
on following patches.
v2: updated after new nir general XFB support introduced for "anv: Add

Technically nir_xfb_info consumer can get the same from the

instead of providing it.

This pulls the guts of function inlining into a builder helper so that

needed for most inlining cases to ensure that everything gets inlined

inline one little thing. This new helper also has a neat trick where it
can seamlessly inline a function from one nir_shader into another.

The lowering we do for 64-bit instructions can cause a single NIR ALU
instruction to blow up into hundreds or thousands of instructions
potentially with control flow. If loop unrolling isn't aware of this,
it can unroll a loop 20 times which contains a nir_op_fsqrt which we
then lower to a full software implementation based on integer math.
Those 20 invocations suddenly get a lot more expensive than NIR loop
unrolling currently expects. By giving it an approximate estimate
function, we can prevent loop unrolling from going to town when it
shouldn't.
