Merge remote-tracking branch 'remotes/stsquad/tags/pull-testing-tcg-plugins-270520-1' into staging

Testing and one plugin fix:

  - support alternates for genisoimage to test/vm
  - add clang++ to clang tests
  - fix record/replay smoke test
  - enable more softfloat tests
  - better detection of hung gdb
  - upgrade aarch64 tcg test x-compile to gcc-10
  - fix plugin cpu_index clash vs threads
