Because we really want it in F12, to make e.g. systemtap usable. It got
quite a lot of testing already and has been in development for 2 years.
Originally it was expected to be merged early in the summer, testing
rawhide gccs have been prepared already in early August.

There were so far 3 bugreports related to this, 2 of them are already fixed,
LLVM build is just needing too much memory on completely insane source
(people calling functions with 1375 arguments, 685 out of it are classes
with non-trivial ctors passed by value, deserve some punishment) and Alex
will look at it today.
