Currently, a buffer can hold 1024 bindless descriptors but

glsl: stop considering unnamed and named structures equal

Previously, if an unnamed and a named struct contained the same fields,
they were considered the same type during linking of globals.

The discussion around commit e018ea81bf58 ("glsl: Structures must have
same name to be considered same type.") doesn't seem to have considered
this thoroughly, and I see no evidence that an unnamed struct should
ever be considered to be the same type as a named struct.

glsl: give all unnamed structs the same name

As a result, unnamed structs defined in different places of the program
are considered the same types if they have the same fields in the same
order.

This will simplify matching of global variables whose type is an unnamed
struct.

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;

   s2 = s1;

C/C++ do not allow that, but GLSL does seem to want to treat unnamed
structs with the same fields as the same type at least during linking
(and apparently, some applications require it), so it seems odd to treat
them as different types elsewhere.
