[mlir:OpAsm] Factor out the common bits of (Op/Dialect)Asm(Parser/Printer)

This has a few benefits:
* It allows for defining parsers/printer code blocks that
  can be shared between operations and attribute/types.
* It removes the weird duplication of generic parser/printer hooks,
  which means that newly added hooks only require touching one class.

[IR] Handle large element size when calculating GEP indices

This is a fix for the issue reported at
The ElementSize is a uint64_t and as such may be larger than the
index space, or be negative in the index space. This is UB, but
shouldn't cause assertion failures.

We address this by detecting whether the size is too large and
use a zero index in that case (which is always conservatively

[SystemZ][z/OS] Introduce the GOFFMCAsmInfo Interface for z/OS

- This patch adds in the GOFFMCAsmInfo interfaces for the z/OS target.
- This patch decouples the previously existing SystemZMCAsmInfo interface for the ELF target and the z/OS target.
- This patch also removes a small test in the SystemZAsmLexerTest.cpp. The reason for this is because, the test is set up for the s390x-ibm-linux (SystemZ ELF triple), and the test checks a function which is overridden only for the z/OS target. The reason we can't change the test to use a z/OS triple outright is because there is still missing support which prevents the successful running of a test (assert in AsmParser.cpp due to missing GOFFAsmParser support)

[mlir] Create a generic reduction detection utility

This patch introduces a generic reduction detection utility that works
across different dialecs. It is mostly a generalization of the reduction
detection algorithm in Affine. The reduction detection logic in Affine,
Linalg and SCFToOpenMP have been replaced with this new generic utility.

The utility takes some basic components of the potential reduction and
returns: 1) the reduced value, and 2) a list with the combiner operations.
The logic to match reductions involving multiple combiner operations disabled
until we can properly test it.

[AutoFDO][llvm-profgen] Profile generation for LBR(non-CS) sample

This patch introduces non-CS AutoFDO profile generation into LLVM. The profile is supposed to be well consumed by compiler using `-fprofile-sample-use=[profile]`.

After range and branch counters are extracted from the LBR sample, here we go through each addresses for symbolization, create FunctionSamples and populate its sub fields like TotalSamples, BodySamples and HeadSamples etc. For inlined code, as we need to map back to original code, so we always add body samples to the leaf frame's function sample.

[AutoFDO][llvm-profgen] Report zero count for unexecuted part of function code

In order to be consistent with compiler that interprets zero count as unexecuted(cold), this change reports zero-value count for unexecuted part of function code. For the implementation, it leverages the range counter, initializes all the executed function range with the zero-value. After all ranges are merged and converted into disjoint ranges, the remaining zero count will indicates the unexecuted(cold) part of the function.

This change also extends the current `findDisjointRanges` method which now can support adding zero-value range.

WIP: Verify -gsimple-template-names=mangled values

Clang will encode names that should be able to be simplified as
"_STNname|<template, args>" (eg: "_STNt1|<int>") - this verification
mode will detect these names, decode them, create the original name
("t1<int>") and the simple name ("t1") - letting the simple name run
through the usual rebuilding logic - then compare the two sources of the
full name - the rebuilt and the _STN encoding.

This helps ensure that -gsimple-template-names is lossless.

[llvm] Improve with help and snapshot

This change adds the ability to create source tarballs for unreleased or untagged code by providing the `--git-ref <GIT_REF>` flag to the `llvm/utils/release/` script. This is useful for creating daily snapshot tarballs that can easily be consumed by packagers who want to build a daily snapshot.

The default behavior of `` hasn't changed.

You may also provide a `--template` argument to say how the artifacts
are supposed to be named (as suggested by @hans).

The `-help` output of `` was changed quite significantly to look like this:

Export the Git sources and build tarballs from them.

Usage: [-release|--release <major>.<minor>.<patch>]
                      [-rc|--rc <num>]
                      [-git-ref|--git-ref <git-ref>]
                      [-template|--template <template>]


  -release  | --release <major>.<minor>.<patch>    The version number of the release
  -rc       | --rc <num>                           The release candidate number
  -final    | --final                              When provided, this option will disable the rc flag
  -git-ref  | --git-ref <git-ref>                  (optional) Use <git-ref> to determine the release and don't export the test-suite files
  -template | --template <template>                (optional) Possible placeholders: $PROJECT $YYYYMMDD $GIT_REF $RELEASE $RC.
                                                   Defaults to '${PROJECT}-${RELEASE}${RC}.src.tar.xz'.

The following list shows the filenames (with <placeholders>) for the artifacts
that are being generated (given that you don't touch --template).

  * llvm-<RELEASE><RC>.src.tar.xz
  * clang-<RELEASE><RC>.src.tar.xz
  * compiler-rt-<RELEASE><RC>.src.tar.xz
  * libcxx-<RELEASE><RC>.src.tar.xz
  * libcxxabi-<RELEASE><RC>.src.tar.xz
  * libclc-<RELEASE><RC>.src.tar.xz
  * clang-tools-extra-<RELEASE><RC>.src.tar.xz
  * polly-<RELEASE><RC>.src.tar.xz
  * lldb-<RELEASE><RC>.src.tar.xz
  * lld-<RELEASE><RC>.src.tar.xz
  * openmp-<RELEASE><RC>.src.tar.xz
  * libunwind-<RELEASE><RC>.src.tar.xz
  * flang-<RELEASE><RC>.src.tar.xz

Additional files being generated:

  * llvm-project-<RELEASE><RC>.src.tar.xz    (the complete LLVM source project)
  * test-suite-<RELEASE><RC>.src.tar.xz      (only when not using --git-ref)

To ease the creation of snapshot builds, we also provide these files

  * llvm-release-<YYYYMMDD>.txt        (contains the <RELEASE> as a text)
  * llvm-rc-<YYYYMMDD>.txt             (contains the rc version passed to the invocation of
  * llvm-git-revision-<YYYYMMDD>.txt   (contains the current git revision sha1)

Example values for the placeholders:

  * <RELEASE>  -> 13.0.0
  * <YYYYMMDD> -> 20210414
  * <RC>       -> rc4        (will be empty when using --git-ref)

In order to generate snapshots of the upstream main branch you could do this for example: --git-ref upstream/main --template '${PROJECT}-${YYYYMMDD}.src.tar.xz'
