[mlir] Add operations to BlockAndValueMapping and rename it to IRMapping

The patch adds operations to `BlockAndValueMapping` and renames it to `IRMapping`. When operations are cloned, old operations are mapped to the cloned operations. This allows mapping from an operation to a cloned operation. Example:

```
Operation *opWithRegion = ...
Operation *opInsideRegion = &opWithRegion->front().front();

IRMapping map
Operation *newOpWithRegion = opWithRegion->clone(map);
Operation *newOpInsideRegion = map.lookupOrNull(opInsideRegion);
```

Migration instructions:
All includes to `mlir/IR/BlockAndValueMapping.h` should be replaced with `mlir/IR/IRMapping.h`. All uses of `BlockAndValueMapping` need to be renamed to `IRMapping`.

[mlir] Trim a huge number of unnecessary dependencies on the Func dialect

The Func has a large number of legacy dependencies carried over from the old
Standard dialect, which was pervasive and contained a large number of varied
operations. With the split of the standard dialect and its demise, a lot of lingering
dead dependencies have survived to the Func dialect. This commit removes a
large majority of then, greatly reducing the dependence surface area of the
Func dialect.

[mlir] Rename the Standard dialect to the Func dialect

The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

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>
}
```
