Added the equivalence operator. The major index optimizations are done.
...
Notes:
1) Some optimizations will follow after more deep analysis.
2) The syntax "==" is not yet agreed on. I'd prefer it to be changed.

MSVC6 doesn't keep variables in a for() only in that scope. This standard construction is rejected:
...
for (int i = ...);
for (int i = ...);
Put the variable again before the loops to be able to compile.

Small optimization of multiple OR booleans (or a constant IN predicate).
...
The idea is to use a single sparse bitmap for an index matching and hence avoid OR'ing bitmaps for every argument value.
Ported from Yaffil.

2) New index structure ensures that NULLs cannot hold the same key-value as a data value.
3) Ignore NULLs already on scanning index where possible.
