[PATCH] Use VAR_P (x) instead of TREE_CODE () == VAR_DECL in config/i386

[Jakub Jelinek]

Hi!

This is a small cleanup patch for i386 backend.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

        * config/i386/i386.c (ix86_in_large_data_p, ix86_expand_builtin): Use
        VAR_P (x) instead of TREE_CODE (x) == VAR_DECL.
