sconstab added a child revision: D76811: [X86] Refactor X86IndirectThunks.cpp to Accomodate Mitigations other than Retpoline [2/3].

There are applications for indirect call/branch thunks other than retpoline for Spectre v2, e.g.,

https://software.intel.com/security-software-guidance/software-guidance/load-value-injection

Therefore it makes sense to refactor X86RetpolineThunks as a more general capability.
