  ThinLTO: Fix inline assembly references to static functions with CFI

Create an internal alias with the original name for static functions
that are renamed in promoteInternals to avoid breaking inline
assembly references to them.

Relands 700d07f8ce6f2879610fd6b6968b05c6f17bb915 with -msvc targets
fixed.
