Split tests.

Split tests.

001: most types, return as array
002: bigint return as float member of an objet (32 bits only)
003: bigint return as string member of an objet (32 bits only)
004: bigint return as integer member of an objet (64 bits only)

The bigint value used is >32bits but <64bits which doesn't exists
in real world (to avoid issue with jsonc used in free distro)
