Vulkan: SPIR-V Gen: Handle gl_PerVertex
If not declared by the shader, default gl_PerVertex is now explicitly
declared in AST prior to SPIR-V generation. The SPIR-V generation code
then doesn't need to declare them magically.

Translator: Fix struct/uniform separation w.r.t to arrays
When a uniform of struct type was redeclared, the arrayness information
was not transferred.

Translator: Fix local var inits vs struct/uniform separation
The declarations outside the global scope were being skipped in this
transformation, but if the initializer of a declaration referenced a
uniform struct that's being replaced, it should have been visited too.

Vulkan: Remove special output of structs and keep them in AST
The code that separated out declaration of nameless structs from uniform
variable declarations is generalized to separate out declaration of all
structs from uniform variable declarations.
As a result, a pass that outputs the struct types at the top of the
shader is no longer necessary. The struct declarations are kept in the
AST to be output to GLSL as they normally would when not used in
conjunction with uniform variables.
After this change, the Vulkan and Metal translators no longer intermix
transformations and code generation; transformations are done first
entirely in AST, and code generation is done at the end.
