[PATCH] D115128: [TableGen][CodeEmitter] Introducing the VarLenCodeEmitterGen infrastructure

[Min-Yih Hsu via Phabricator via llvm-commits]

- Addressed minor issues.
- Replace `const APInt InstBits[] =...` with two integer arrays to avoid static global ctor.

Now we will have two arrays, `Index` and `InstBits` that look like this:

  unsigned Index[][2] = {
    {/*NumBits*/87, /*Index to InstBits*/0}, // FOO16
    {/*NumBits*/39, /*Index to InstBits*/2}, // FOO32
  };
  uint64_t InstBits[] = {
    UINT64_C(<fixed values>), UINT64_C(...), // FOO16
    UINT64_C(...),  // FOO32
  };
