[SanitizerCoverage] Give clang-cc1 the power to precisly specify needed sanitizier coverage mode. Summary: The next step is to add user-friendly control over these options to driver via -fsanitize-coverage= option.

[MSan] add KMSAN support to Clang driver Boilerplate code for using KMSAN instrumentation in Clang. We add a new command line flag, -fsanitize=kernel-memory, with a corresponding SanitizerKind::KernelMemory, which, along with SanitizerKind::Memory, maps to the memory_sanitizer feature. KMSAN is only supported on x86_64 Linux. It's incompatible with other sanitizers, but supports code coverage instrumentation. llvm-svn: 341641

[Driver] Improve unused-argument diagnostic for extra sanitizer features. Don't print unused-argument warning for sanitizer-specific feature flag if this sanitizer was eanbled, and later disabled in the command line. For example, now: clang -fsanitize=address -fsanitize-coverage=bb -fno-sanitize=address a.cc doesn't print warning, but clang -fsanitize-coverage=bb does. Same holds for -fsanitize-address-field-padding= and -fsanitize-memory-track-origins= flags. Fixes PR23604. llvm-svn: 237870

[sancov] add tracing for loads and store add tracing for loads and stores. The primary goal is to have more options for data-flow-guided fuzzing, i.e. use data flow insights to perform better mutations or more agressive corpus expansion. But the feature is general puspose, could be used for other things too. Pipe the flag though clang and clang driver, same as for the other SanitizerCoverage flags. While at it, change some plain arrays into std::array. Tests: clang flags test, LLVM IR test, compiler-rt executable test.

[sancov] add tracing for loads and store add tracing for loads and stores. The primary goal is to have more options for data-flow-guided fuzzing, i.e. use data flow insights to perform better mutations or more agressive corpus expansion. But the feature is general puspose, could be used for other things too. Pipe the flag though clang and clang driver, same as for the other SanitizerCoverage flags. While at it, change some plain arrays into std::array. Tests: clang flags test, LLVM IR test, compiler-rt executable test.
