Evgeniy Stepanov 075e6aecf1 [msan] Put msan constructor in a comdat. ...

MSan adds a constructor to each translation unit that calls
__msan_init, and does nothing else. The idea is to run __msan_init
before any instrumented code. This results in multiple constructors
and multiple .init_array entries in the final binary, one per
translation unit. This is absolutely unnecessary; one would be
enough.

This change moves the constructors to a comdat group in order to drop
the extra ones.
