hlopko b987fd2ae5 Introduce structured build variables in Crosstool ... This cl adds a 3rd type of build variable - structs. Structs have fields, which can hold any build variable type (including structs). In the CROSSTOOl, the fields are accessed by the dot-notation, e.g.: flag_group { iterate_over: "libraries_to_link flag_group { iterate_over: "libraries_to_link.libraries" flag: "-L%{libraries_to_link.libraries.directory}" } } As a memory optimization, we also add StructureSequences. These save us from the overhead of individual StructureValue objects. RELNOTES: NONE PiperOrigin-RevId: 138851774		2019-01-09 08:51:24 +01:00
