Build fix for the newer bison environment

With the older bison, yyparse prototype is not contained in the generated header file1.

However, the newer bison (I'm using 3.0.2 on Ubuntu 14.04) generates the header file with the yyparse prototype.
The yyparse prototype is declared with the parameter types. Since parser::PTXParser::State is nested class, we cannot add forward declaration into the generated header. And since PTXParser.h and yyparse prototype have a circular reference, we cannot include PTXParser.h in the generated ptxgrammar.hpp.

To solve it, I've created the patch for PTXLexer.h. In this patch, we provides yyparse macro definition to avoid generating yyparse prototype. I think it is relatively stable solution for the generated header by bison.

Could you review this patch?
