This reverts commit 4c863993780a11cea6f88fa0682796bee5794042. The commit was erroneous because the ast_layout_expression class was created to hold a list of values for a layout-qualifier-name which is allowed to appear in more than one expression in the same shader/program but not to hold different values.
In other words, the list is used for an after check that all the declared values for a layout-qualifier-name are consistent. Therefore, the values stored must match always, not just for "max_vertices" or any other eventual layout-qualifier-name.
