giles 16df723e08 js-on-sx: numeric keys in object literals stringify on parse ...

{0: 41, 1: 42} was raising 'dict-set!: dict key val' because the parser
kept numeric keys as numbers in the entry dict, but SX dicts require string
keys. Now we str-coerce number-type tokens during jp-parse-object-entry.
Unblocks a huge chunk of test262 array-like-receiver tests that build
{length: N, 0: v, 1: v, ...} literals.

3 new tests, 453/455 total.
