This series enables objtool to start doing stack validation and orc

Based on Julien's previous work(1)(2), Now I have finished most of work
for objtool enable on arm64. This series includes objtool part [1-13]
and arm64 support part [14-33], the second part is to make objtool run
correctly with no warning on arm64 so if necessary it can be taken apart
as two series.

ORC generation feature is implemented but not used because we don't have
an unwinder_orc on arm64, now it only be used to check whether objtool
has correct validation.

This series depends on (https://lkml.org/lkml/2022/6/22/463)
I moved some changes which work for all architectures to that series
because this one becomes too big now.
And it is rebased to tip/objtool/core branch.

What is the sha1 of the base?

With b4 and git am the patch series is derailing at patch 6 and I'm even
after a bit of fixup (had to use rediff) I'm still getting a cascade of
errors in later patches to decode.c .
