721a1f53df perf tests: Pass the subtest index to each test routine 
Some tests have sub-tests we want to run, so allow passing this.

Wang tried to avoid having to touch all tests, but then, having the
test.func in an anonymous union makes the build fail on older compilers,
like the one in RHEL6, where:

  test a = {
	.func = foo,
  };

fails.

To fix it leave the func pointer in the main structure and pass the subtest
index to all tests, end result function is the same, but we have just one
function pointer, not two, with and without the subtest index as an argument.

a5e813c686 perf machine: Add method for common kernel_map(FUNCTION) operation 
And it is also a step in the direction of killing the separation of data
and text maps in map_groups.

1eee78aea9 perf tools: Introduce struct maps 
That for now has the maps rbtree and the list for the dead maps, that
may be still referenced from some hist_entry, etc.

This paves the way for protecting the rbtree with a lock, then refcount
the maps and finally remove the removed_maps list, as it'll not ne
anymore needed.

c080f72753 perf tests: No need to set up ref_reloc_sym 
Now that ref_reloc_sym is set up by machine__create_kernel_maps(), the
"vmlinux symtab matches kallsyms" test does have to do it.

82e75d00ad perf tests: Adjust the vmlinux symtab matches kallsyms test again 
The kallsyms maps now may map to kcore and the symbol values now may be
file offsets.  For comparison with vmlinux the virtual memory address is
needed which is obtained by unmapping the symbol value.

The "vmlinux symtab matches kallsyms" is adjusted accordingly.

Omitting end of the function check failure for test 1, since there's no
way to get exact symbol end via kallsyms.
