Yes, globalopt does that.

You're asking two questions:

1. Does llvm incorrectly assume things that break C++ constructors and the 
GNU extensions.
2. Does llvm assume things that break kernels.

The answer to #1 is no.  The answer to #2 is "not if you use 
-ffree-standing".  Why do you care about globalopt.cpp specifically?
