Description Michael Saboff 2016-07-19 12:58:28 PDT 
On ARM64 bots, we started seeing failures running
    mozilla-tests.yaml/ecma/FunctionObjects/15.3.1.1-3.js.mozilla-ftl-eager-no-cjit-validate-phases
    mozilla-tests.yaml/ecma/FunctionObjects/15.3.2.1-3.js.mozilla-ftl-eager-no-cjit-validate-phases
    mozilla-tests.yaml/ecma/FunctionObjects/15.3.5-1.js.mozilla-ftl-eager-no-cjit-validate-phases

Below is the log output for one of the failures.  Possibly a RELEASE_ASSERT.
