Add support for Subpass Input proposal of issue #1069. Subpass input types are given as: layout(input_attachment_index = 1) SubpassInput<float4> subpass_f; layout(input_attachment_index = 2) SubpassInput<int4> subpass_i; layout(input_attachment_index = 3) SubpassInput<uint4> subpass_u; layout(input_attachment_index = 1) SubpassInputMS<float4> subpass_ms_f; layout(input_attachment_index = 2) SubpassInputMS<int4> subpass_ms_i; layout(input_attachment_index = 3) SubpassInputMS<uint4> subpass_ms_u; The input attachment may also be specified using attribute syntax: [[vk::input_attachment_index(7)]] SubpassInput subpass_2; The template type may be a shorter-than-vec4 vector, but currently user structs are not supported. (An unimplemented error will be issued). The load operations are methods on objects of the above type: float4 result = subpass_f.SubpassLoad(); int4 result = subpass_i.SubpassLoad(); uint4 result = subpass_u.SubpassLoad(); float4 result = subpass_ms_f.SubpassLoad(samp); int4 result = subpass_ms_i.SubpassLoad(samp); uint4 result = subpass_ms_u.SubpassLoad(samp); Additionally, the AST printer could not print EOpSubpass* nodes. Now it can. Fixes #1069
