Reviewed by Geoffrey Garen.

This is pretty cool. Anywhere we previously printed Structure pointers in dumps,
we now print a bunch of other info as well. For example, for an object literal
like "{f:42, g:64, h:24}", when we print the structure we'll now get:

    0x107a0af80:[Object, {f:0, g:1, h:2}, NonArray, Proto:0x107a8fff0]

This also changes a bunch of places to use the dump method.
