  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. This version uses module inline assembly
to avoid issues with LowerTypeTestsModule.

Relands commmit 8e3b5cb39eef462943ed7556469604ce25c07a1d with arch
specific tests fixed.
