MSL: Support input/output blocks containing nested struct arrays Fixes numerous CTS tests of types dEQP-VK.pipeline.interface_matching.vector_length.member_of_*, passing complex nested structs between stages as stage I/O. - Make add_composite_member_variable_to_interface_block() recursive to allow struct members to contain nested structs, building up member names and access chains recursively, and only add the resulting flattened leaf members to the synthetic input and output interface blocks. - Recursively generate individual location numbers for the flattened members of the input/output block. - Replace to_qualified_member_name() with append_member_name(). - Update add_variable_to_interface_block() to support arrays as struct members, adding a member to input and output interface blocks for each element of the array. - Pass name qualifiers to add_plain_member_variable_to_interface_block() to allow struct members to be arrays of structs, building up member names and access chains, and adding multiple distinct flattened leaf members to the synthetic input and output interface blocks. - Generate individual location numbers for the individual array members of the input/output block. - SPIRVCrossDecorationInterfaceMemberIndex references the index of a member of a variable that is a struct type. The value is relative to the variable, and for structs nested within that top-level struct, the index value needs to take into consideration the members within those nested structs. - Pass var_mbr_idx to add_plain_member_variable_to_interface_block() and add_composite_member_variable_to_interface_block(), start at zero for each variable, and increment for each member or nested member within that variable. - Add unit test shaders-msl/vert/out-block-with-nested-struct-array.vert - Add unit test shaders-msl/vert/out-block-with-struct-array.vert - Add unit test shaders-msl/tese/in-block-with-nested-struct.tese 2022-02-26 00:58:22 +00:00			`#version 450`
