13bd410962 [mlir][Pass] Include anchor op in -pass-pipeline
In D134622 the printed form of a pass manager is changed to include the
name of the op that the pass manager is anchored on. This updates the
`-pass-pipeline` argument format to include the anchor op as well, so
that the printed form of a pipeline can be directly passed to
`-pass-pipeline`. In most cases this requires updating
`-pass-pipeline='pipeline'` to
`-pass-pipeline='builtin.module(pipeline)'`.

This also fixes an outdated assert that prevented running a
`PassManager` anchored on `'any'`.

3655069234 [mlir] Move the Builtin FuncOp to the Func dialect
This commit moves FuncOp out of the builtin dialect, and into the Func
dialect. This move has been planned in some capacity from the moment
we made FuncOp an operation (years ago). This commit handles the
functional aspects of the move, but various aspects are left untouched
to ease migration: func::FuncOp is re-exported into mlir to reduce
the actual API churn, the assembly format still accepts the unqualified
`func`. These temporary measures will remain for a little while to
simplify migration before being removed.

92ccb8cc50 [MLIR][NFC] Update SCF pass cmd line names to prefix scf
Update SCF pass cmd line names to prefix `scf`. This is consistent with
guidelines/convention on how to name dialect passes. This also avoids
ambiguity on the context given the multiple `for` operations in the
tree.

a54f4eae0e [MLIR] Replace std ops with arith dialect ops
Precursor: https://reviews.llvm.org/D110200

Removed redundant ops from the standard dialect that were moved to the
`arith` or `math` dialects.

Renamed all instances of operations in the codebase and in tests.

f8479d9de5 [mlir] Set the namespace of the BuiltinDialect to 'builtin'
Historically the builtin dialect has had an empty namespace. This has unfortunately created a very awkward situation, where many utilities either have to special case the empty namespace, or just don't work at all right now. This revision adds a namespace to the builtin dialect, and starts to cleanup some of the utilities to no longer handle empty namespaces. For now, the assembly form of builtin operations does not require the `builtin.` prefix. (This should likely be re-evaluated though)

3f429e82d3 Implement an scf.for range folding optimization pass.
In cases where arithmetic (addi/muli) ops are performed on an scf.for loops induction variable with a single use, we can fold those ops directly into the scf.for loop.

For example, in the following code:

```
scf.for %i = %c0 to %arg1 step %c1 {
  %0 = addi %arg2, %i : index
  %1 = muli %0, %c4 : index
  %2 = memref.load %arg0[%1] : memref<?xi32>
  %3 = muli %2, %2 : i32
  memref.store %3, %arg0[%1] : memref<?xi32>
}
```

we can lift `%0` up into the scf.for loop range, as it is the only user of %i:

```
%lb = addi %arg2, %c0 : index
%ub = addi %arg2, %i : index
scf.for %i = %lb to %ub step %c1 {
  %1 = muli %0, %c4 : index
  %2 = memref.load %arg0[%1] : memref<?xi32>
  %3 = muli %2, %2 : i32
  memref.store %3, %arg0[%1] : memref<?xi32>
}
```
