zikaeroh 6b9e3f883e cmd/compile: don't emit write barriers for offsets of global addresses 
Currently, write barriers aren't emitted for global addresses, but they
are emitted for addresses offset of global addresses.

This CL changes IsGlobalAddr to recognize offsets of global addresses
as globals too, removing write barriers for staticuint64s based
addresses. The logic added is the same as used in IsStackAddr.

Updates #37612
