22426110c5 mlir/tblgen: use std::optional in generation
This is part of an effort to migrate from llvm::Optional to
std::optional. This patch changes the way mlir-tblgen generates .inc
files, and modifies tests and documentation appropriately. It is a "no
compromises" patch, and doesn't leave the user with an unpleasant mix of
llvm::Optional and std::optional.

A non-trivial change has been made to ControlFlowInterfaces to split one
constructor into two, relating to a build failure on Windows.

1a36588ec6 [mlir] Use std::nullopt instead of None (NFC)
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

1fa870b1bd Use None consistently (NFC)
This patch replaces NoneType() and NoneType::None with None in
preparation for migration from llvm::Optional to std::optional.

In the std::optional world, we are not guranteed to be able to
default-construct std::nullopt_t or peek what's inside it, so neither
NoneType() nor NoneType::None has a corresponding expression in the
std::optional world.

Once we consistently use None, we should even be able to replace the
contents of llvm/include/llvm/ADT/None.h with something like:

  using NoneType = std::nullopt_t;
  inline constexpr std::nullopt_t None = std::nullopt;

to ease the migration from llvm::Optional to std::optional.

d85eb4e2d6 [AsmParser] Introduce a new "Argument" abstraction + supporting logic
MLIR has a common pattern for "arguments" that uses syntax
like `%x : i32 {attrs} loc("sourceloc")` which is implemented
in adhoc ways throughout the codebase.  The approach this uses
is verbose (because it is implemented with parallel arrays) and
inconsistent (e.g. lots of things drop source location info).

Solve this by introducing OpAsmParser::Argument and make addRegion
(which sets up BlockArguments for the region) take it.  Convert the
world to propagating this down.  This means that we correctly
capture and propagate source location information in a lot more
cases (e.g. see the affine.for testcase example), and it also
simplifies much code.

5dedf911de [AsmParser] Rework logic around "region argument parsing"
The asm parser had a notional distinction between parsing an
operand (like "%foo" or "%4#3") and parsing a region argument
(which isn't supposed to allow a result number like #3).

Unfortunately the implementation has two problems:

1) It didn't actually check for the result number and reject
   it.  parseRegionArgument and parseOperand were identical.
2) It had a lot of machinery built up around it that paralleled
   operand parsing.  This also was functionally identical, but
   also had some subtle differences (e.g. the parseOptional
   stuff had a different result type).

I thought about just removing all of this, but decided that the
missing error checking was important, so I reimplemented it with
a `allowResultNumber` flag on parseOperand.  This keeps the
codepaths unified and adds the missing error checks.
