cfallin opened PR #1833 from multi-value-loop to master:

It appears that the CLIF generation for a branch to a loop label did not taken into account the possibility of loop-block parameters. I believe the correct semantics here (at least as far as I understood the spec) are to pop new versions of the loop params off the stack at the point of the branch.

This PR fixes spec/multi-value/block-run.wast in the newer version of spec_testsuite, which we aren't yet using in the wasmtime tree but which SpiderMonkey is. This bug was caught during integration of the multivalue work with SpiderMonkey.

(The loop-params.wast test added in this PR is the one particular failing case from block-run.wast.)
