btf: add BTF_KIND_FUNC traversal function.
The patch adds a traversal function to traverse all BTF_KIND_FUNC nodes
with a callback function. Used for .BTF.ext section content creation.
gcc/ChangeLog:
* btfout.cc (output_btf_func_types): Use FOR_EACH_VEC_ELT.
(traverse_btf_func_types): Define function.
* ctfc.h (funcs_traverse_callback): Typedef for function
prototype.
(traverse_btf_func_types): Add prototype.
