Design doc: https://docs.google.com/document/d/1AsUCqslMUB6fLdnGq0ZoPk2kn50jIJAWAL77lKXXP5g/

Currently, wasm loop unrolling is disabled by default. We intend to
further investigate its compilation time cost and running time benefits
before enabling it.

Additional changes:
- Introduce LoopFinder::FindUnnestedLoopFromHeader() as a lightweight
  loop analysis.
- Move EliminateLoopExit into LoopPeeling and expose it.
- Introduce loop_info_ field into WasmGraphBuildingInterface, fill it
  up in Loop().
- Break after encountering the first loop in BuildNestedLoopExits.
- Introduce struct WasmLoopInfo. A WasmLoopInfo vector is instantiated
  in ExecuteTurbofanWasmCompilation, passed to BuildGraphForWasmFunction
  to be filled up by WasmGraphBuildingInterface, and then passed to
  GenerateCodeForWasmFunction to be used in WasmLoopUnrollingPhase.
- Introduce WasmLoopUnrollingPhase and insert it into the wasm
  compilation pipeline.
- Fix an issue where exception values were not wrapped in
  WasmGraphBuilderInterface.
- Update --wasm-loop-unrolling flag description.

WasmGraphBuilder often failed to use GraphAssembler infrastructure and
went with directly invoking graph()->NewNode(). This made the code more
verbose, especially in cases where effect() and control() had to be
passes directly to NewNode().
This CL eliminates these invocations in obvious cases. It does not try
to refactor complicated code with branches, diamond patterns, etc.

Additional changes:
- Define a few more operators in GraphAssembler.
- Move Branch() helper in WasmGraphAssembler.
- Define NumberConstant() helper in WasmGraphAssembler.
- Define Merge() helper with varargs in WasmGraphBuilder.
- Omit IntPtrConstant() wrapper for constant offsets of Load and Store.
