c++, tree: declare some basic functions inline
The functions strip_array_types, is_typedef_decl, typedef_variant_p
and cp_expr_location are used throughout the C++ front end including in
some fairly hot parts (e.g. in the tsubst routines and cp_walk_subtree)
and they're small enough that the overhead of calling them out-of-line
is relatively significant.
So this patch moves their definitions into the appropriate headers to
enable inlining them.
gcc/cp/ChangeLog:
* cp-tree.h (cp_expr_location): Define here.
* tree.cc (cp_expr_location): Don't define here.
