Revert [gasm] Implement ReduceArrayPrototypeReduce using the graph assembler

Reverting due to a nondeterministic correctness issue bisected to this
change. The intent is to reland once we fully understand and have
fixed the problem.

The original CL landed in https://crrev.com/c/1934329.
The revert on master is https://crrev.com/c/2049763.
The revert on 8.0 is https://crrev.com/c/2049764.
