LNUM patch Good Friday revise

[Asko Kauppi <askok@...>]

Happy Easter, everyone.

There's been some fixes to LNUM patch, mostly concerning optimizations  
on x86 and x86_64 platforms. All known cases of crashing are now solved.

For people using LNUM succesfully on embedded arena, there's nothing  
much new. But having the fixes done makes me feel better since there's  
no unknown issues now.

The LNUM patch allows easy and wide configuration of Lua number types,  
with the use of simple compiler defines (LNUM_INT32, LNUM_INT64,  
LNUM_FLOAT, LNUM_DOUBLE, LNUM_LDOUBLE, LNUM_COMPLEX). It provides  
added integer accuracy (32- or 64-bit), enhances speed on non-FPU  
systems and allows use of complex numbers (C99 required).
