The implementations of folding for the intrinsic functions SCALE and SET_EXPONENT
do not cope correctly with numbers in the subnormal range. Fix SCALE,
then modify SET_EXPONENT to be a special case of SCALE.

Prior to this patch, the `add_tablegen()` macro in
llvm/cmake/modules/TableGen.cmake added the install rule only if
`project` matched `LLVM` or `MLIR`. This patch adds an optional
`DESTINATION` argument, which, if non-empty, decides whether (and where)
to install the tablegen tool, thus eliminating the need for
project-specific overrides. This patch also updates all other
invocations of the `add_tablegen()` macro.

We need to distinguish BLOCK host association from subprogram host
association when checking assignments in PURE subprograms.
The specific case that is not allowed is an assignment to a variable
from the scope around the PURE subprogram.

1dcff823db9 updated the ORC runtime to use std::string_view, rather than its
own placeholder class (__orc_rt::string_view), but failed to add these
includes.

Since C++17 the message string for static_assert is optional. Replaces
static asserts with an empty string literal with the single-argument

When an I/O statement contains a function call that attempts
to perform I/O on the same unit, detect the recursive I/O
and terminate with a useful message rather than deadlocking in
the threading library.

This reverts commit 6ea5bf436a983ea9e16a5fe7534c87beca0a61b7.
6ea5bf436a983ea9e16a5fe7534c87beca0a61b7 made use of new c++17 rules regarding
order of evaluation (specifically: in function calls the expression naming the
function should be sequenced before the evalution of any operands) to simplify
some continuation-passing calls. Unfortunately this appears to break at least
one MSVC bot: https://lab.llvm.org/buildbot/#/builders/123/builds/12149 .
Includes an update to the comments to note that the workaround is now based on
MSVC limitations, not on LLVM adopting c++17.

Change the `<enum>_to_str` functions in lldbutil to be dynamic.
Instead of a manually maintained if/elif switch, the functions now perform
lookup in a dynamically generated dict. The names are determined by stripping
the enum's prefix, and then lowercasing the remaining suffix, ex:
eStateRunning -> "running"

Swift calling conventions stands out in the way that they are lowered in
mostly target-independent manner, with very few customization points.
As such, swift-related methods of ABIInfo do not reference the rest of
ABIInfo and vice versa.
This change follows interface segregation principle; it removes
dependency of SwiftABIInfo on ABIInfo. Targets must now implement
SwiftABIInfo separately if they support Swift calling conventions.
Almost all targets implemented `shouldPassIndirectly` the same way. This
de-facto default implementation has been moved into the base class.
`isSwiftErrorInRegister` used to be virtual, now it is not. It didn't
accept any arguments which could have an effect on the returned value.
This is now a static property of the target ABI.

F18 disallows function references and coarray references from
appearing in scalar expressions that are to be expanded into
arrays to conform with other operands or actual arguments in
an elemental expression. This is too strong, as pure procedures
can be safely used.

I went over the output of the following mess of a command:
`(ulimit -m 2000000; ulimit -v 2000000; git ls-files -z | parallel --xargs -0 cat | aspell list --mode=none --ignore-case | grep -E '^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n | grep -vE '.{25}' | aspell pipe -W3 | grep : | cut -d' ' -f2 | less)`
and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).

The pattern matching optimization of Polly detects and optimizes dense general
matrix-matrix multiplication. The generated code is close to high performance
implementations of matrix-matrix multiplications, which are contained in
manually tuned libraries. The described pattern matching optimization is
a particular case of tensor contraction optimization, which was
introduced in [1].
This patch generalizes the pattern matching to the case of tensor contractions
using the form of data dependencies and memory accesses produced by tensor
contractions [1].
Optimization of tensor contractions will be added in the next patch. Following
the ideas introduced in [2], it will logically represent tensor contraction
operands as matrix multiplication operands and use an approach for
optimization of matrix-matrix multiplications.

Now that C++17 is enabled in LLVM, a lot of the TODOs and patterns to emulate C++17 features can be eliminated.
The steps I have taken were essentially:
```
git grep C++17
git grep c++17
git grep "initializer_list<int>"
```
and address given comments and patterns.
Most of the changes boiled down to just using fold expressions rather than initializer_list.
While doing this I also discovered that Clang by default restricts the depth of fold expressions to 256 elements. I specifically hit this with `TestDialect` in `addOperations`. I opted to not replace it with fold expressions because of that but instead adding a comment documenting the issue.
If any other functions may be called with more than 256 elements in the future we might have to revert other parts as well.
I don't think this is a common occurence besides the `TestDialect` however. If need be, this could potentially be fixed via `mlir-tblgen` in the future.

**Motivation: ** I have been studying LLVM with LLVM Kaleidoscope tutorial. In the 4th part I faced an error which said that I can't redefine a function as shown in the tutorial. After hours of searching, I finally found the reason that produced the error is that the feature of symbols redefinition has been disabled since LLVM-9. There was no information about that in the tutorial's text, so I've decided to add a warning.
**Changes**: The only file I fixed is "`llvm/docs/tutorial/MyFirstLanguageFrontend/LangImpl04.rst`", I added text warning which says that described feature is outdated and the described functionality will not work properly on LLVM versions older 8 one.
