1. context_id shouldn't be read during update.
2. EagerExecutor::state_ should be set before creating EagerExecutor::thread_

It is too specific and not widely used to be maintained as a part of TF's API.

Prefer to enumerate all cases in the switch instead of using default to allow
compiler to flag missing cases. This also avoids -Wcovered-switch-default
warning.

When comparing CacheKeys we cannot simply compare the namedtuple fields
since that might involve comparing 2 Variables whose equality comparison
returns a Tensor rather than a bool. We thus compare Variables using
their class name, dtype & shape, similar to the processing we do for the
hash.

This can result in index expression overflow in "Loc.getPointer() - ColumnNo"
in SourgeMgr.

loc could also be prefixed to the message additionally in this case.

Every new instance of TfLiteGlCompileOptions should be populated through DefaultTfLiteGlCompileOptions() call to avoid breaking changes when new option is introduced.

This instruction is a local counterpart of llvm.global that takes a symbol
reference to a global and produces an SSA value containing the pointer to it.
Used in combination, these two operations allow one to use globals with other
operations expecting SSA values.  At a cost of IR indirection, we make sure the
functions don't implicitly capture the surrounding SSA values and remain
suitable for parallel processing.

This CL is step 3/n towards building a simple, programmable and portable vector abstraction in MLIR that can go all the way down to generating assembly vector code via LLVM's opt and llc tools.

This CL adds support for converting MLIR n-D vector types to (n-1)-D arrays of 1-D LLVM vectors and a conversion VectorToLLVM that lowers the `vector.extractelement` and `vector.outerproduct` instructions to the proper mix of `llvm.vectorshuffle`, `llvm.extractelement` and `llvm.mulf`.

This has been independently verified to produce proper avx2 code.

Input:
```
func @vec_1d(%arg0: vector<4xf32>, %arg1: vector<8xf32>) -> vector<8xf32> {
  %2 = vector.outerproduct %arg0, %arg1 : vector<4xf32>, vector<8xf32>
  %3 = vector.extractelement %2[0 : i32]: vector<4x8xf32>
  return %3 : vector<8xf32>
}
```

Command:
```
mlir-opt vector-to-llvm.mlir -vector-lower-to-llvm-dialect --disable-pass-threading | mlir-opt -lower-to-cfg -lower-to-llvm | mlir-translate --mlir-to-llvmir | opt -O3 | llc -O3 -march=x86-64 -mcpu=haswell -mattr=fma,avx2
```

Output:
```
vec_1d:                                 # @vec_1d
# %bb.0:
        vbroadcastss    %xmm0, %ymm0
        vmulps  %ymm1, %ymm0, %ymm0
        retq
```
