This is a more canonical type name, and is in line with {kVoidCode}.

Tail calls are connected to the end of the graph, so technically they
also constitute loop exits.
Additional Changes:
- In DoReturnCall, change the argument {Node* index_node} into
{Value index_or_caller_value}.
- Rename StackValueVector -> ValueVector.
- Add a test that reveals the bug.

Changes:
- In graph-builder-interface.cc, move loop exit utilities in the private
section.
- In the same functions, remove SsaEnv argument. Always use ssa_env_
instead.
- Introduce TerminateThrow, which introduces loop exits before inserting
a throw node.
- Introduce loop exits in the exception handling opcodes.
- Introduce control_depth_of_current_catch() helper.
- Drive-by: Add an optional missing 'break' in DoReturnCall.
- Add some tests, improve test flags in loop-unrolling.js test file.

Changes:
- Add --wasm-loop-unrolling flag. Everything in this CL happens behind
this flag.
- In decoding, DoReturn does not take returned values as an argument.
It is now the responsibility of graph-builder-interface.cc to extract
these values. Note that this is what was already happening in Liftoff.
- In pipeline.cc, add phase to remove loop exits after generating the
turbofan graph.
- Explicitly disallow calling FallThruTo() on loops.
- Add loop assignments and loop header node to Control type in
graph-builder-interface.cc. Assign them in Loop().
- Main change: Add loop exit nodes to wasm-generated graphs. For
details, consult this design doc: https://docs.google.com/document/d/1AsUCqslMUB6fLdnGq0ZoPk2kn50jIJAWAL77lKXXP5g
- Inline PrepareForLoop().
