fnsplit: Set musttail call during function splitting if there are musttail calls [PR119376]
The just posted inliner patch can regress musttail calls if we perform
function splitting and then inline the outlined body back into the original
(or inline both the small function and outlined large body into something
else).
If there are any musttail calls, I think we need to call the outlined
body using a musttail call, so that the inliner will preserve musttail
attributes in the body.

on the call to outlined partition if has_musttail and
!add_tsan_func_exit.
