Proxy objects need special treatment in toString(). Usually, we use the
@@toStringTag, if it is set, otherwise we determine the result of toString()
by checking IsArray() and other internal slots. According to
ES2017 19.1.3.6, IsArray() and the internal slots  must be checked first,
then get(@@toStringTag). The result of IsArray() and internal slots is discarded if
@@toStringTag is set. For proxy
objects, we must obey this order, because get() can have side-effects, i.e.,
revoke the proxy. For all other objects, we can skip the check of the
internal slots, if @@toStringTag is set.

We deviate from spec in that, in our implementation, __defineGetter__ on non-
configurable properties returns false instead of throwing a TypeError. This commit
adds a use counter to track how often we would be throwing an error we currently
avoid, to determine if we can change to align with spec or if the spec is not
implementable.

The hash field is supposed to be 4 bytes even in 64-bit. But the
default parameter of StoreObjectFieldNoWriteBarrier using kTagged
will generate 64-bit store. Fix by Replacing kTagged with kWord32.

This causes ~200 test failures on big-endian, because hash field
offset in BE is 12 instead of 8 in LE platforms.
