[flang] Version information in flang/f18

Fixed some version information in flang/f18:

  - fixed the behavior of the -v switch: this flag enables verbosity with used with arguments, but just displays the version when used alone (related to this bug: https://bugs.llvm.org/show_bug.cgi?id=46017)
- added __FLANG, __FLANG_MAJOR__, __FLANG_MINOR__ and __FLANG_PATCHLEVEL__ (similar to their __F18* counterparts) for compatibility purpose

[Bitstream] Use alignTo to make code more readable. NFC

I was recently debugging a similar issue to https://reviews.llvm.org/D86500 only with a large metadata section. Only after I finished debugging it did I discover it was fixed very recently.

My version of the fix was going to alignTo since that uses uint64_t and improves the readability of the code. So I though I would go ahead and share it.

[libfuzzer] Reduce default verbosity when printing large mutation sequences

When using a custom mutator (e.g. thrift mutator, similar to LPM)
that calls back into libfuzzer's mutations via `LLVMFuzzerMutate`, the mutation
sequences needed to achieve new coverage can get prohibitively large.

Printing these large sequences has two downsides:

1) It makes the logs hard to understand for a human.
2) The performance cost slows down fuzzing.

In this patch I change the `PrintMutationSequence` function to take a max
number of entries, to achieve this goal. I also update `PrintStatusForNewUnit`
to default to printing only 10 entries, in the default verbosity level (1),
requiring the user to set verbosity to 2 if they want the full mutation
sequence.

For our use case, turning off verbosity is not an option, as that would also
disable `PrintStats()` which is very useful for infrastructure that analyzes
the logs in realtime. I imagine most users of libfuzzer always want those logs
in the default.

I built a fuzzer locally with this patch applied to libfuzzer.

When running with the default verbosity, I see logs like this:

Staring hard at the logs it's clear that the cap of 10 is applied.

When running with verbosity level 2, the logs look like the below:

These are prohibitively large and of limited value in the default case (when
someone is running the fuzzer, not debugging it), in my opinion.

[fuzzer] Create user provided fuzzer writeable directories when requested if they dont exist

Currently, libFuzzer will exit with an error message if a non-existent
directory is provided for any of the appropriate arguments. For cases
where libFuzzer is used in a specialized embedded environment, it would
be much easier to have libFuzzer create the directories for the user.

This patch accommodates for this scenario by allowing the user to provide
the argument `-create_missing_dirs=1` which makes libFuzzer attempt to
create the `artifact_prefix`, `exact_artifact_path`,
`features_dir` and/or corpus directory if they don't already exist rather
than throw an error and exit.

Split off from D84808 as requested [here](https://reviews.llvm.org/D84808#2208546).

Revert "Revert "Reapply D70800: Fix AArch64 AAPCS frame record chain""

This reverts commit bc9a29b9ee6ade4894252b1470977142c32b4602.

The reasoning that this patch was wrong was itself incorrect
(see discussion on llvm-commits). This patch does seem to be exposing
a latent SVE code generation bug on non-public tests, which should
not block a correctness fix for public, non-SVE use cases.

Do not emit "-tune-cpu generic" for PS4 platform

For the PS4, do not emit "-tune-cpu generic" since the platform only has 1 known CPU and we do not want to prevent optimizations by tuning for a generic rather than the specific processor it contains.

[MachineCopyPropagation] In isNopCopy, check the destination registers match in addition to the source registers.

Previously if the source match we asserted that the destination
matched. But GPR <-> mask register copies on X86 can violate this
since we use the same K-registers for multiple sizes.

[LV] Interleave to expose ILP for small loops with scalar reductions.

Interleave for small loops that have reductions inside,
which breaks dependencies and expose.

This gives very significant performance improvements for some benchmarks.
Because small loops could be in very hot functions in real applications.

Commit 0d966ae4b2ac0344e15888d0f0a81c322e3d6dd2 by flo
[Loads] Add canReplacePointersIfEqual helper.

This patch adds an initial, incomeplete and unsound implementation of
canReplacePointersIfEqual to check if a pointer value A can be replaced
by another pointer value B, that are deemed to be equivalent through
some means (e.g. information from conditions).

Note that is in general not sound to blindly replace pointers based on
equality, for example if they are based on different underlying objects.

LLVM's memory model is not completely settled as of now; see
https://bugs.llvm.org/show_bug.cgi?id=34548 for a more detailed
discussion.

The initial version of canReplacePointersIfEqual only rejects a very
specific case: replacing a pointer with a constant expression that is
not dereferenceable. Such a replacement is problematic and can be
restricted relatively easily without impacting most code. Using it to
limit replacements in GVN/SCCP/CVP only results in small differences in
7 programs out of MultiSource/SPEC2000/SPEC2006 on X86 with -O3 -flto.

This patch is supposed to be an initial step to improve the current
situation and the helper should be made stricter in the future. But this
will require careful analysis of the impact on performance.
