<pre>Currently UpdateCompilerUsed handles functions that the backend can introduce
references to. They are added to llvm.compiler_used.
For example, if we pass llvm-lto this input
define void @memcpy() {
ret void
}
the output will have
@llvm.compiler.used = appending global [1 x i8*] [i8* bitcast (i8* (i8*, i8*,
i64)* @memcpy to i8*)], section "llvm.metadata"
It should do the same for variables the backend can introduce an use.
__stack_chk_guard is one such variable, but there may be others.
With this in place we can then delete the hard coded handling of
__stack_chk_guard in internalize.</pre>
