This patch moves prototype of char_type_p into c-common.h, so we can
use it in c-family/*.
gcc/ChangeLog:
2017-06-12 Xi Ruoyao <r...@stu.xidian.edu.cn>
* c-family/c-common.h (char_type_p): New prototype.
* c/c-typeck.c (char_type_p): Make the function extern.
* cp/cp-tree.h (char_type_p): Remove prototype.
* cp/tree.c (char_type_p): Change the return type to bool.
