29167bbff8 Add qlpack.json files 
Eventually these files will subsume the current `queries.xml` files
at the top of query-containing and library directories. For now they're
just here to support internal testing of the tooling support for them
we're writing on.

Format and contents is a work in progress. If you're not in Semmle,
don't depend on anything here making sense (or staying stable) until
you see the version tags increase to something nonzero.

0990ceb09a C++: Remove bbNotInLoop and its caller in FlowVar 
This change is needed when enabling the QL CFG on certain snapshots such
as notaz/picodrive. It removes the `bbNotInLoop` predicate, which was
always a liability because it's inherently quadratic. The real slowdown
came in `skipLoop`, where all true-upon-entry loops were crossed with
all definitions of variables that should take their definition from the
loop body.

eed24f1933 C++: Improve join orders with QL CFG 
Size estimates are slightly different when we enable the QL CFG, and
this caused bad join orders in these predicates.

34b625900a C++: Avoid extends Operation in LeapYear.qll 
The `Operation` class is abstract, and extending it caused cached stages
to be recomputed all the way down to the AST. This meant that the leap
year queries evaluated their own copy of SSA and data flow.
