[mlir][EmitC] Expand the MemRefToEmitC pass - Lowering CopyOp (#151206)
This patch lowers `memref.copy` to `emitc.call_opaque "memcpy"`.
From:
```
func.func @copying(%arg0 : memref<9x4x5x7xf32>, %arg1 : memref<9x4x5x7xf32>) {
  memref.copy %arg0, %arg1 : memref<9x4x5x7xf32> to memref<9x4x5x7xf32>
  return
}
```
To:
```cpp
#include <cstring>
void copying(float v1[9][4][5][7], float v2[9][4][5][7]) {
  size_t v3 = 0;
  float* v4 = &v2[v3][v3][v3][v3];
  float* v5 = &v1[v3][v3][v3][v3];
  size_t v6 = sizeof(float);
  size_t v7 = 1260;
  size_t v8 = v6 * v7;
  memcpy(v5, v4, v8);
  return;
}
```

[mlir][EmitC]Expand the MemRefToEmitC pass - Lowering AllocOp (#148257)
This aims to lower `memref.alloc` to `emitc.call_opaque “malloc” ` or
`emitc.call_opaque “aligned_alloc” `
From:
```
module{
  func.func @allocating() {
  %alloc_5 = memref.alloc() : memref<999xi32>
  return
  }
}
```

To:
```
module {
  emitc.include <"stdlib.h">
  func.func @allocating() {
    %0 = emitc.call_opaque "sizeof"() {args = [i32]} : () -> !emitc.size_t
    %1 = "emitc.constant"() <{value = 999 : index}> : () -> index
    %2 = emitc.mul %0, %1 : (!emitc.size_t, index) -> !emitc.size_t
    %3 = emitc.call_opaque "malloc"(%2) : (!emitc.size_t) -> !emitc.ptr<!emitc.opaque<"void">>
    %4 = emitc.cast %3 : !emitc.ptr<!emitc.opaque<"void">> to !emitc.ptr<i32>
    return
  }
}
```
Which is then translated as:
```
#include <stdlib.h>
void allocating() {
  size_t v1 = sizeof(int32_t);
  size_t v2 = 999;
  size_t v3 = v1 * v2;
  void* v4 = malloc(v3);
  int32_t* v5 = (int32_t*) v4;
  return;
}
```

[mlir][EmitC] memref-to-emitc: insert conversion_casts (#114204)
Add materializations to the conversion pass, such that types of
non-converted operands are legalized.

[MLIR] Add initial convert-memref-to-emitc pass (#85389)
This converts `memref.alloca`, `memref.load` & `memref.store` to
`emitc.variable`, `emitc.subscript` and `emitc.assign`.
