    gccrs: [E0703] Use of Invalid ABI
    
    Added error code support for invalid ABI.
    
    gcc/rust/ChangeLog:
    
            * hir/rust-ast-lower-base.cc (ASTLoweringBase::lower_qualifiers):
            called error function.
            (ASTLoweringBase::lower_extern_block): likewise.
    
    gcc/testsuite/ChangeLog:
    
            * rust/compile/abi-options1.rs: updated comment for testcase.
