Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

Reduce contention on the Attributes lock by using atomic operations for reference counting rather than locking.

has an index or something else incompatible), because it has a
smaller encoding.

Describing inbounds in terms of infinitely precise arithmetic prohibits
the assumption address-space-sized integer arithmetic will wrap, with
a wrapped-around value landing within the same object.

Although this does not make the CFG more correct, it makes the CFG more 
beautiful without multiple roots.
