[DFSan] Remove -dfsan-args-abi support in favor of TLS. ArgsABI was originally added in https://reviews.llvm.org/D965 Current benchmarking does not show a significant difference. There is no need to maintain both ABIs. Reviewed By: pcc Differential Revision: https://reviews.llvm.org/D111097

[dfsan] Increase coverage of vector and select tests Add more expectations in vector.ll and select.ll based on command-line option combinations. Also, remove hard-coded shadow width references to enable fast8 transition. Reviewed By: stephan.yichao.zhao Differential Revision: https://reviews.llvm.org/D97903

[dfsan] Remove hard-coded shadow width in more tests As a preparation step for fast8 support, we need to update the tests to pass in both modes. That requires generalizing the shadow width and remove any hard coded references that assume it's always 2 bytes.

DataFlowSanitizer: wrappers of functions with local linkage should have the same linkage as the function being wrapped This patch resolves link errors when the address of a static function is taken, and that function is uninstrumented by DFSan. This change resolves bug 36314. Patch by Sam Kerner! Differential Revision: https://reviews.llvm.org/D44784 llvm-svn: 328890
