This CL also moved the UniformSupport.cpp and FakeQuantSupport.cpp into utils because they are not really the core of the IR.

For ops with the SameValueType trait, we generate a builder without requiring
result type; we get the result type from the operand. However, if the operand
is variadic, we need to index into the first value in the pack.

There are no empty lines in output for three of these directives so removed
them and replaced the remaining one with 'CHECK-NOT:' as otherwise it is

Now, op attribute names don't have '.' in their names so the special handling for it
can be removed. Attributes for functions still have dialect prefix with '.' as separator but TableGen does not deal with functions.

Iterators for a `llvm::DenseMap` can be invalidated when an insertion occurs.
In Pattern's `collectBoundArguments()`, we recursively handle all nested DAG
nodes and grow the the `RecordOperatorMap`, while retaining a reference.
This can cause the reference to be invalid and the program to behave randomly.
Allocate each `Operator` object specifically to solve this issue.
Also, `llvm::DenseMap` is a great way to map pointers to pointers, or map
other small types to each other. This avoids placing the `Operator` object
directly into the map.

This CL changes various predicates and rewrite rules to use $-placeholders and
`tgfmt` as the driver for substitution. This will make the predicates and rewrite
rules more consistent regarding their arguments and more readable.

Currently predicates are written with positional placeholders `{N}` and rely on
`formatv` as the engine to do substitution. The problem with this approach is that
the definitions of those positional placeholders are not consistent; they are
entirely up to the defining predicate of question. For example, `{0}` in various
attribute constraints is used to mean the attribute, while it is used to main the
builder for certain attribute transformations. This can become very confusing.
This CL introduces `tgfmt` as a new mechanism to better support for predicate and
rewrite rule specification. Instead of entirely relying on positional placeholders,
`tgfmt` support both positional and special placeholders. The former is used for
DAG operands. The latter, including $_builder, $_op, $_self, are used as special
"hooks" to entities in the context. With this, the predicate and rewrite rules
specification can be more consistent is more readable.

This allows client to be able to reuse the same logic to setup a module
for the ExecutionEngine without instanciating one. One use case is running
the optimization pipeline but not JIT-ing.

When an op in the source pattern specifies more arguments than its definition, we
will have out-of-bound query for op arguments from the definition. That will cause
crashes. This change fixes it.

TensorContractionBase has become too unwieldy with all the CRTP manipulation once less trivial transformations are implemented.
This CL drops CRTP for inheritance and uses the same name comparison trick to figure out what to cast into.
As a byproduct, all the -inl.h files disappear.
To maintain the separation between directories, a LINALG_STEP variable is introduced

For some reason, the OSS build on macOS was not happy with the initialization

This is only teaching the LLVM converter to propagate the attribute onto
the function type. MLIR will not recognize this arguments, so it would only
be useful when calling for example `printf` with the same arguments across
a module. Since varargs is part of the ABI lowering, this is not NFC.
