eval("const[]=*,[x]=r")

causes an [infer failure] Unknown bytecode: enumconstelem then a crash on both js debug and opt shells with -m, -n and -a on JM changeset 511f51584aad.
Handle the JSOP_ENUMCONSTELEM opcode during inference.  I'm reasonably sure this opcode is never used in js/src/tests or js/src/jit-test (other than the test this adds).
