Bill Hollings 0c0fd98322 MSL: Use var name instead of var-type name for flattened interface members.
This allows two variables of the same struct type to be flattened
into the same interface struct without a member name conflict.

Add shaders-msl/frag/in_block_with_multiple_structs_of_same_type.frag
unit test shader to demonstrate this.
