Instance-type-related fixes and cleanup.

Things got quite a bit out of sync (don't we all love copy-n-paste?):

   * TypeToString didn't handle SLICED_STRING_TYPE,
     SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
     JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.

   * INSTANCE_TYPE_LIST was missing entries for
     SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.

To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.

Removed INVALID_TYPE on the way, it had no real use.
