80b0765618 C++: Make IR DataFlow dispatch use non-IR version

the support for flow across link targets.

6ef946c2b0 C++: Make IR TaintTracking available on LGTM

imported here in order to be available in the LGTM query console.

d310338c9b C++: Implement dominanceFrontier with recursion 
This implementation is borrowed from Java's QL library and offers a
great performance improvement. For example, on Wireshark the performance
goes from

    Dominance::bbDominates#ff ....... 40.3s
    SSAUtils::dominanceFrontier#ff .. 30s

to

    SSAUtils::dominanceFrontier#ff .. 418ms (executed 67 times)

The big performance problem before was the need to materialize
`bbDominates`, which is the reflexive-transitive "basic block dominates"
relation. It had 79 million rows on Wireshark.

4f9ffb38e6 C++: Set cpp/command-line-injection precision=low 
This query is only appropriate for setuid programs. Since such programs
are at most 0.1% of all code we analyse, I would say this query has a
precision of at most 0.1%.

This fixes false positives on
https://lgtm.com/projects/g/brandonpelfrey/Construct caused by a member
function named `gets` -- probably short for "get s".
