[MSan] Remove explicit -m64 from RUN lines. Target-specific flags should usually be configured by CMake/lit. llvm-svn: 230999

[MSAN][MIPS] Fix fork.cc test on MIPS Summary: For platforms which support slow unwinder only, we restrict the store context size to 1, basically only storing the current pc. We do this because the slow unwinder which is based on libunwind is not async signal safe and causes random freezes in forking applications as well as in signal handlers. Reviewed by eugenis.

[msan] Origin tracking with history, compiler-rt part. Compiler-rt part of MSan implementation of advanced origin tracking, when we record not only creation point, but all locations where an uninitialized value was stored to memory, too. llvm-svn: 204152

[msan] Fix bad interaction between with-calls mode and chained origin tracking. Origin history should only be recorded for uninitialized values, because it is meaningless otherwise. This change moves __msan_chain_origin to the runtime library side and makes it conditional on the corresponding shadow value. Previous code was correct, but _very_ inefficient. llvm-svn: 211700
