Reducing the memory footprint, but more has to be done, such as to take
advantage of the strings table when handling indirect strings.

So that we can find all the cus for some specific class
(cus__find_class_by_name), or traverse all the CUs (cus__for_each_cu),
etc.
Now we don't look at just the first CU in multi-CU files (vmlinux, etc).

types for each CU, for now when working on multi-CU files (vmlinux, any binary
with more than one object file linked) we look only at the first CU when
looking for a specific class or function name, this will be fixed in the
upcoming csets, but doesn't affect the case when we don't specify a class or
function name, where all the CU's are traversed.

except for --classes, that asks that all non-inlined functions that receive as
one of its parameter a pointer to the specified class be printed, just the name

name is passed.

struct foo {
char c:1;
int b:1;
short a:1;
};
the first byte_size for the first member (c) will be 1, as the "type"
is char, but the compiler combines all of them into a single 4 byte
bitfield, and the '4' only appear when the bit field has type int, in
the above case on the second member.
