[PATCH] diagnostic: fix for older version of GCC

[Marc Poulhiès]

Having both an enum and a variable with the same name triggers an error with
gcc 5.

ChangeLog:

        * c/gcc/diagnostic-state-to-dot.cc (get_color_for_dynalloc_state):
        Rename argument dynalloc_state to dynalloc_st.
        (add_title_tr): Rename argument style to styl.
        (on_xml_node): Rename local variable dynalloc_state to dynalloc_st.
---
Bootstrapped on x86_64-linux using GCC 5.5.0. 
Ok for master?
