Vulkan: Simplify pulling samplers out of structs The RewriteStructSampler transformation moves samplers out of structs, for example turning this struct: struct Original { sampler2D s1; vec4 f1; sampler2D s2; sampler2D s3; vec4 f2; }; into: struct Modified { vec4 f1; vec4 f2; }; This required modifying the struct-field selection nodes to remap the field indices, causing some complication. Instead, this change makes the struct definition reorder the fields as such right during parse: struct Original { vec4 f1; vec4 f2; sampler2D s1; sampler2D s2; sampler2D s3; }; As a result, the field-selection indices for non-sampler fields don't get changed when the struct is replaced with `Modified`.
