ThinLTOBitcodeWriter: Emit __cfi_check to full LTO part of bitcode file.
The CrossDSOCFI pass runs on the full LTO module and fills in the
body of __cfi_check. This function must have the correct attributes in
order to be compatible with the rest of the program. For example, when
building with -mbranch-protection=standard, the function must have the
branch-target-enforcement attribute, which is normally added by Clang.
When __cfi_check is missing, CrossDSOCFI will give it the default set
of attributes, which are likely incorrect. Therefore, emit __cfi_check
to the full LTO part, where CrossDSOCFI will see it.
