[PATCH] [MSan][Clang][MIPS] Enabled memory, dataflow and thread options for MIPS platform

[Alexey Samsonov]

IIRC we had problems when we enabled the feature with a few tests still failing, and immediately got complaints from users, whose LLVM build started to fail "check-all" command.
I agree that it's hard to use and test the tool w/o Driver support. But I'd like to see the order of landing patches that would keep the MIPS build green.

E.g. I'm OK with landing the change to the driver before enabling building/testing of a specific sanitizer runtime.
