Looks reasonable, but in the test coverage I see uses of `gcc_jit_context_get_target_info` and `gcc_jit_target_info_supports_target_dependent_type`; is this dependent on another patch? (and is that one stuck on review?)
Alternatively, this could lose the parts of the test coverage that use `gcc_jit_target_info` and go ahead into trunk. -- https://forge.sourceware.org/gcc/gcc-TEST/pulls/74#issuecomment-2228
