86431a2f1c new opcodes BANDK/BORK/BXORK. (They do not use immediate operands
because, too often, masks in bitwise operations are integers larger
than one byte.)

9fa1baf6de opcodes for order and shift can use several metamethods,
so it is better to use a generic description + metamethod names
in some error messages shown without '__' prefix

196c87c9ce no more 'stackless' implementation; 'luaV_execute' calls itself
recursively to execute function calls. 'unroll' continues all
executions suspended by an yield (through a long jump)

5440b42f43 using 'trap' to stop 'luaV_execute' when necessary (tracing and

b42430fd3a 'lineinfo' in prototypes saved as differences instead of absolute
values, so that the array can use bytes instead of ints, reducing
its size. (A new array 'abslineinfo' is used when line differences
do not fit in a byte.)
