Roberto Ierusalimschy 4d5de1c1fb Fixed bug in line info. when using 'not' operator 
When creating code for a jump on a 'not' condition, the code generator
was removing an instruction (the OP_NOT) without adjusting its
corresponding line information.

This fix also added tests for this case and extra functionality in
the test library to debug line info. structures.

Roberto Ierusalimschy b08c9079c5 Opcode names moved to a new header file 
The array with the names of the opcodes was moved to a header file
('lopnames.h'), as it is not used by the Lua kernel. Files that need
that array ('luac.c' and 'ltests.c') include the header file to get
a private (static) copy.

Roberto Ierusalimschy 5a1c8d8ef3 new constant 'LUA_GNAME' for the name of the global table "_G" 2017-06-27 15:32:49 -03:00
Roberto Ierusalimschy 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.)
 2017-06-27 08:35:31 -03:00
Roberto Ierusalimschy 73ec04fcf3 no more 'DEADKEY'. Table traversals do not need to consider dead keys; 
if the key is dead, it cannot be given to 'next'. Instead, we now
use a 'table' tag without the collectable bit, which makes it
a unique tag good enough to reserve space.
