[WPD]: Enable speculative devirtualizatoin. (#159048)

This patch implements the speculative devirtualization feature in the
LLVM backend.
It handles the case of single implementation devirtualization where
there is a single possible callee of a virtual function.
- Add cl::opt 'devirtualize-speculatively' to enable it.
- Flag is disabled by default.
- It works regardless of the visibility of the object.
- Not enabled for LTO for now.
