native code for bitwise operators in LUA

["Ing. Jan Supuka SBM" <sbmintegral@...>]

In newest LUA 5.2 beta is implemented UNSIGNED INTEGER type and library 
bit32 for bitwise operations.
BEAUTIFULL !

But I don't like write
    a = bit32.bor(bit32.band(5,2345),bit32.band(23,7))
instead of
    a = 5&2345|23&7
that's why I rework source codes ( lua-5.2.0-beta.tar.gz [NEW]     
2011-07-08
                                
http://www.lua.org/work/lua-5.2.0-beta.tar.gz )
to use "native" operators (based on 
http://www.wra1th.plus.com/lua/risclua.html source code) :
    band &
    bor     |
    bxor    ^^
    lshift <<
    rshift >>
    bnot    ~
and my own logical operators:
    and &&
    or      ||
    not     !

All source code changes are dependent on (luaconfig.h)
#define GCW_BIT
/*
GCW_BIT: Use bit library.
This extends virtual machine with bitwise operations
&,|, ^^, ~, <<, >> and provides corresponding events.
Warning! Makes code non-portable.
Affects c.lvm, c.lcode, c.lopcodes, c.ltm
c.llex, c.lparser, h.lcode, h.lopcodes
h.ltm, h.llex, h.luaconf.

additionally NUM_logical operators ( return numerical (1,0), not boolean 
values )
!,&&,||
*/

IMPORTANT:   in standart LUA is not possible use boolean (true,false) in 
arithmetical operations,
but I need it.
On (lvm.c line:375) is it possible (unremark) allow using booleans only 
for new operators.

Need tests, if all is correct.

BASIC TEST ... approximately 5x faster native versus bit32.bxxx 
operators,  more readable LUA source
