The microbenchmark doubly-recursive fib(37) is slower with cranelift than with ion: cranelift/ion = 1.13 at present on lth's Xeon dev system with Fedora.

See https://github.com/lars-t-hansen/embenchen/tree/master/micro for details: wasmfib.js for the benchmark code, wasmfib.md for running analysis of the machine code.

Specific work items to fix this discrepancy will be blockers of this bug.
