mesa: add infrastructure for bindless samplers/images bound to units

Yes, ARB_bindless_texture allows to do this. In other words, in
a situation like:

layout (bindless_sampler) uniform sampler2D tex;

The 'tex' sampler uniform can be either set with glUniform1()
(old-style bound samplers) or with glUniformHandleui() (resident
handles).

When glUniform1() is used, we have to somehow make the texture
resident "under the hood". This is done by requesting a texture
handle to the driver, making the handle resident in the current
context and overwriting the value directly in the constant buffer.

As a result, unnamed structs defined in different places of the program

It also fixes a memory leak when the same shader containing unnamed
structs is compiled over and over again: instead of creating a new type
each time, the existing type is re-used.

Finally, this does have the effect that some previously rejected programs
are now accepted, such as:

   struct {
      float a;
   } s1;

   struct {
      float a;

   s2 = s1;

C/C++ do not allow that, but GLSL does seem to want to treat unnamed

7 years agoradv: set fmask state to all 0s when no fmask. (v2)

radv: set fmask state to all 0s when no fmask. (v2)

The shader reads the descriptor to decide if it should take the
fmask value, however we weren't initing it always, which meant
random crap, esp with MSAA depth textures.
