[CLASSES]: Don't pass the function pointer to the childs in cu__process_function
...
This is very hackish, see the previous cset comment, without this hack
unrelated, deeper DW_TAG_formal_parameter tags were being attributed to the
function being processed, proper fix is described in previous comment, for now
this is enough as a bandaid.

[CLASSES]: Process DW_TAG_{union,structure}_type tags in cu__process_function
...
There are cases where just a declaration is emitted, such as in
blk_rq_map_user_iov's iov parameter:
<2><dc04>: Abbrev Number: 29 (DW_TAG_structure_type)
DW_AT_name : (indirect string, offset: 0x3be8): sg_iovec
DW_AT_declaration : 1
<2><dc0a>: Abbrev Number: 88 (DW_TAG_formal_parameter)
DW_AT_name : iov
DW_AT_decl_file : 1
DW_AT_decl_line : 2472
DW_AT_type : <dc60>
DW_AT_location : 0x4288 (location list)
I.e. the DW_TAG_structure_type tag is emitted at the same level as the
DW_TAG_formal_parameter tags, so handled inside the cu__process_function
method.
This and the next cset only shows that a normalization in the parsing routines
is in real demand and will be done, normalization because what needs to be done
is similar to what is already done in places like cu__create_new_array, i.e.
process all the siblings in a level in tag specific cu methods.

So far struct class was being used as the main data structure, switch to struct
tag, that already was the top of the tag hierarchy, being a struct class
ancestor, so reflect that and stop using struct class as the catch all class,
as a started DW_TAG_array_type tags are now represented by a new class, struct
array_type, reducing the size of struct class and reducing DW__TAG_array_type

Now we're getting to the point where a better, non printk based relaying module
is in demand, will look at blktrace relayfs stuff.
Getting access to the traced parameter at kretprobes time is badly needed, so
that we can correlate the exit calls with the entry ones.

If a definition is being emitted and there was already a forward declaration,

list, in the reverse case just don't add it to the fwd_decl list.

So that we can build a module that doesn't uses #includes to get these

More work to be done for enums, etc, but this already is enough for
ctracer to handle tracing the sk_buff methods in vmlinux.
