From: Michael Roth <mdroth@linux.vnet.ibm.com>
We never actually stored the stringified double values into the strings
before we did the comparisons. This left number/double values completely
uncovered in test-visitor-serialization tests.
Fixing this exposed a bug in our handling of large whole number values
in QEMU's JSON parser which is now fixed.
Simplify the code while we're at it by dropping the
calc_float_string_storage() craziness in favor of GStrings.
