[ThinLTO/CFI] Include TYPE_ID summaries into GLOBALVAL_SUMMARY_BLOCK Summary: TypeID summaries are used by CFI and need to be serialized by ThinLTO indexing for later use by LTO Backend.

; REQUIRES: x86-registered-target
; Backend test for distribute ThinLTO with CFI.
[LTO] Add option to enable LTOUnit splitting, and disable unless needed Summary: Adds a new -f[no]split-lto-unit flag that is disabled by default to control module splitting during ThinLTO. It is automatically enabled for -fsanitize=cfi and -fwhole-program-vtables. The new EnableSplitLTOUnit codegen flag is passed down to llvm via a new module flag of the same name. Depends on D53890.
