Summary: This disables Linux/amd64 builds in Travis for PRs, and adds a gcc-10+c++20 build in CircleCI, which should fill out sufficient coverage vs. what we had in Travis Fixed a use of std::is_pod, which is deprecated in c++20 Fixed ++ on a volatile in db_repl_stress.cc, with bigger refactoring. Although ++ on this volatile was probably ok with one thread writer and one thread reader, the code was still overly complex. There was a deadcode check for error `if (replThread.no_read < dataPump.no_records)` which can be proven never to happen based on the structure of the code. It infinite loops instead for the case intended to be checked. I just simplified the code for what should be the same checking power. Also most configurations seem to be using make parallelism = 2 * vcores, so fixing / using that.
