[Andrea Corallo]

branch: feature/native-comp
commit 5b41545f1be367837d9ac717ea67fba19a4c24d4

    * Better error handling after calling 'gcc_jit_context_compile_to_file'
    
    Tipically errors are catched in 'compile_function' but in case
    libgccjit throw an error only afterwards while compiling the whole
    compilation unit we have to report it correctly.
    
        * src/comp.c (Fcomp__compile_ctxt_to_file): Catch libgccjit
        errors after calling 'gcc_jit_context_compile_to_file'.
