[COMMITTED 25/43] gccrs: Update test with builtin macro definition

[arthur . cohen]

From: Pierre-Emmanuel Patry <pierre-emmanuel.pa...@embecosm.com>

Those test contain builtin macros that were not correctly defined. This
was mostly fine because the compiler emitted attribute errors before the
expansion step but now that the new builtin attribute checking is
executed after the expansion we cannot ignore those missing definitions.

gcc/testsuite/ChangeLog:

        * rust/compile/doc_macro.rs: Add concat builtin macro definition.
        * rust/compile/early_feature_gate_in_macro.rs: Add stringify builtin
        macro definition.
        * rust/compile/issue-3661.rs: Likewise.
        * rust/compile/parse_time_feature_gate.rs: Add concat and stringify
        builtin macro definition.
