483c2ccd0f avoid using raw representation of numbers for hashing, as number may 
not use all its space (e.g., long double can have sizeof=12 but
use only 10 bytes)

f45177f2d3 In the table that hashes constants, use a light userdata as keys 
to integer values to avoid collisions with floats with the same
numerical value

a3e1c40d6d remove of unecessary luaD_checkstack. (In some cases, C should 
ensure stack space; in others, Lua can use the extra slots for
temporary values.)

4758113043 change in opcode OP_LOADNIL: B is used as a counter instead of a 
register. (Avoids an assignment to R(B), not present in any other
instruction.)

1b4480003b "stange numbers" (-0 and NaN) also go to the constant table (as 
strings with their binary representation). Therefore, constant
folding may produce these results.
