Regenerate LC_CODE_SIGNATURE during llvm-objcopy operations
**Context:**
This is a second attempt at introducing signature regeneration to llvm-objcopy. In this diff: https://reviews.llvm.org/D109840, a script was introduced to test
the validity of a code signature. In this diff: https://reviews.llvm.org/D109803 (now reverted), an effort was made to extract the signature generation behavior out of LLD into a common location for use in llvm-objcopy. In this diff: https://reviews.llvm.org/D109972 it was decided that there was no appropriate common location and that a small amount of duplication to bring signature generation to llvm-objcopy would be better. This diff introduces this duplication.
**Summary**
Prior to this change, if a LC_CODE_SIGNATURE load command
was included in the binary passed to llvm-objcopy, the command and
associated section were simply copied and included verbatim in the
new binary. If rest of the binary was modified at all, this results
in an invalid Mach-O file. This change regenerates the signature
rather than copying it.
The code_signature_lc.test test was modified to include the yaml
representation of a small signed MachO executable in order to
effectively test the signature generation.

[lld-macho] Associate compact unwind entries with function symbols
Compact unwind entries (CUEs) contain pointers to their respective
function symbols. However, during the link process, it's far more useful
to have pointers from the function symbol to the CUE than vice versa.
This diff adds that pointer in the form of `Defined::compactUnwind`.
In particular, when doing dead-stripping, we want to mark CUEs live when
their function symbol is live; and when doing ICF, we want to dedup
sections iff the symbols in that section have identical CUEs. In both
cases, we want to be able to locate the symbols within a given section,
as well as locate the CUEs belonging to those symbols. So this diff also
adds `InputSection::symbols`.
The ultimate goal of this refactor is to have ICF support dedup'ing
functions with unwind info, but that will be handled in subsequent
diffs. This diff focuses on simplifying `-dead_strip` --
`findFunctionsWithUnwindInfo` is no longer necessary, and
`Defined::isLive()` is now a lot simpler. Moreover, UnwindInfoSection no
longer has to check for dead CUEs -- we simply avoid adding them in the
first place.
Additionally, we now support stripping of dead LSDAs, which follows
quite naturally since `markLive()` can now reach them via the CUEs.

code that may intend to iterate on the results or the operands could end up "working"

[NFC] [LoopPeel] Update IDoms of non-loop blocks dominated by the loop
When peeling a loop, we assume that the latch has a `br` terminator and that
all loop exits are either terminated with an `unreachable` or have a terminating
deoptimize call. So when we peel off the 1st iteration, we change the IDom of
all loop exits to the peeled copy of `NCD(IDom(Exit), Latch)`. This works now,
but if we add logic to support loops with exits that are followed by a block
with an `unreachable` or a terminating deoptimize call, changing the exit's idom
wouldn't be enough and DT would be broken.
For example, let `Exit1` and `Exit2` are loop exits, and each of them
unconditionally branches to the same `unreachable` terminated block. So neither
of the exits dominates this unreachable block. If we change the IDoms of the
exits to some peeled loop block, we don't update the dominators of the unreachable
block. Currently we just don't get to the peeling logic, saying that we can't peel
such loops.
Previously we stored exits' IDoms in a map before peeling a loop and then, after
peeling off one iteration, we changed their IDoms.
Now we use the same logic not only for exits but for all non-loop blocks dominated
by the loop.
So when we add logic to support peeling loops with exits which branch, for example,
to an unreachable-terminated block, we would update the IDoms not only for exits,
but for their successors.
