Instead of computing these two things in one predicate, they are
computed in separate predicates and then joined. This splits the
predicate `getInstruction`, which took 81s before, into predicates that
together take 20s on a medium-sized db.
Moved IR flavors into "implementation", with internal files under "implementation/internal". Made `IRBlockConstruction` just a nested module of `IRConstruction`/`SSAConstruction`, so it gets picked up from the `Construction` parameter of the `IR` module, rather than being picked up just from being in the same directory as `IRBlock`.
This change makes the public IR.qll module resolve to the flavor of the IR that we want queries to use. Today, this is the aliased SSA flavor of the IR. Should we add additional IR iterations in the future, we'll update IR.qll to resolve to whichever one we consider the default.
I moved the PrintIR.ql and IRSanity.ql queries into the internal directories of the corresponding flavors. There's still a PrintIR.ql and an IRSanity.ql in the public IR directory, which use the same IR flavor as the public IR.qll.
There are no real code changes here, other than to fix up `import`s. All tests still hae the same output, as expected.
A future commit will hide the IR flavors other than the one we want queries to use directly.
Globals can still have declarations in declaration statements.
We already rule out local variables etc via the isTopLevel check,
so we don't need to consider DeclStmt.

predicate `primitive_basic_block_member`, which took 77s before, into
predicates that together take 18s on a medium-sized db.
By extending this class, a class can define its own `getLocation`
predicate without participating in the dispatch hierarchy of
`getLocation` as defined on `Element`. Classes wanting to override their
location previously had to define `getURL` or `hasLocationInfo` instead
and rely on these predicates not being defined on future versions of
`Element`.
gmtime and gmtime_r take a time_t pointer, so have to store the value
of time(NULL) on the stack.
