[Linux-kernel-mentees] [RFC PATCH 05/25] parsing_c: parser: Add expression statement attributes

As per GCC's C grammar, the expression statement rule has the following
production:

	expression-statement:
  	  gnu-attributes ;

Add this production to the expr_statement rule of Coccinelle's C parser.
If attributes are recognized, this parses the following code
successfully:

	label: attribute;
