[clang][CodeGen] add fn_ret_thunk_extern to synthetic fns
Follow up fix to
commit 2240d72f15f3 ("[X86] initial -mfunction-return=thunk-extern
support")
https://reviews.llvm.org/D129572
@nathanchance reported that -mfunction-return=thunk-extern was failing
to annotate the asan and tsan contructors.
https://lore.kernel.org/llvm/Ys7pLq+tQk5xEa%2FB@dev-arch.thelio-3990X/
I then noticed the same occurring for gcov synthetic functions.
Similar to
commit 2786e67 ("[IR][sanitizer] Add module flag "frame-pointer" and set
it for cc1 -mframe-pointer={non-leaf,all}")
define a new module level MetaData, "fn_ret_thunk_extern", then when set
adds the fn_ret_thunk_extern IR Fn Attr to synthetically created
Functions.
