Ok.

I cleaned things up using variably_modified_type_p() as you did, instead 
of the INTEGER_CST nonsense.  Attached are the latest dwarf2out.c 
changes against mainline.

Jason are you ok with the attached wrt VLAs?  If so, I'm putting this 
aside while I work on DECL_ABSTRACT and friends, and hopefully wrap 
things up.

Tested on x86-64 Linux, gcc and gdb testsuites.

Thanks guys.
