Prototype load lane instructions on ARM Liftoff.
We had a helper function for load lane that was living in
instruction-selector. Move it out to assembler-arm so we can reuse that
in Liftoff.

Offsets in regular expressions are limited to 16 bits.
It was possible to exceed this limit when emitting greedy loops where
the length of text nodes exceeded 16 bits, resulting in overflowing
offsets.
With this CL we throw a SyntaxError "Regular expression too large" to
prevent this overflow.

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

Prototype load lane instructions on ARM64 Liftoff.
We extract a helper function that will convert a MemOperand that uses a
register offset or a non-zero immediate offset, into a MemOperand that
uses a temporary to store base+offset and immediate offset of 0. Some
instructions, ld1r or ld1 don't support offset, and will use this helper
to get the correct MemOperand.
