The CloneFunctionInto has implicit requirements with regards to the
linkage and visibility of the function. We now update these after we did
the CloneFunctionInto on the copy with the same linkage and visibility
as the original.
One run line was different and probably introduced for the manually
added function attribute & name checks. We can do this with the script
and a check prefix used for the other run lines as well.
Even though `noundef` IR attribute might be attached to non-void type values, AANoUndef is mistakenly identified for pointer type values only.
This patch fixes that.

Currently, although we handle `CallBase` case in updateImpl, we give up in initialize in the case.
That is problematic when we propagate a range from call site returned position to floating position.

This patch internalize non-exact functions and replaces of their uses
with the internalized version. Doing this enables the analysis of
non-exact functions.
We can do this because some non-exact functions with the same name
whose linkage is `linkonce_odr` or `weak_odr` should have the same
semantics, so we can safely internalize and replace use of them (the
result of the other version of this function should be the same.).
Note that not all functions can be internalized, e.g., function with
`linkonce` or `weak` linkage.
For now when specified in commandline, we internalize all functions
that meet the requirements without calculating the cost of such
internalzation.
