Fix in the definition of 'sizeLclosure'
The array at the end of a Lua closure has pointers to upvalues, not
to tagged values. This bug cannot cause any issue: The ISO C standard
requires that all pointers to structures have the same representation,
so sizeof(TValue*) must be equal to sizeof(UpVal*).
