[PATCH] [Compiler-rt][Sanitizer][MSan][i386] Adding support for i386

[Evgeniy Stepanov]

Are you sure you are testing i386? :)
It would require changes to lib/msan/tests/CMakeLists.txt and something under test/msan, and this CL does not touch those files. I've tried this patch and 32-bit tests are not getting built.
