Accepting request 895887 from devel:tools:statica

- Update to version 2.2+20210510: * allocate memory objects for functions * differentiate between partial and completed paths in summary and fix paths stats when not dumping states * posix runtime: add malloc checks * Fix erroneous klee-stats legend for --print-all * Replaced the time-based delay * Refactored maxStaticPctChecks into a sequence of conditions. * Added a warning when forking is skipped due to MaxStatic*Pct limits being reached * Added -max-static-pct-check-delay to replace the hardcoded delay after which the MaxStatic*Pct checks are performed. * klee-replay: Fix -Wformat-truncation warning - Switch to LLVM 12. (patches from pr#1389 + 1) * 0001-llvm12-VectorType-getNumElements-has-been-deprecated.patch * 0002-llvm12-Add-LLVM-12-to-lit.cfg.patch * 0005-llvm12-Implement-llvm.-s-u-max-min-intrinsics.patch * 0006-llvm11-Handle-llvm.roundeven-instrinsic.patch * 0007-llvm12-Implement-llvm.abs-intrinsic.patch * 0001-test-disable-until-it-is-fixed.patch OBS-URL: https://build.opensuse.org/request/show/895887 OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/klee?expand=0&rev=27
