Arnold Schwaighofer b40f14eb89 LoopVectorizer: Truncate i64 trip counts of i32 phis if necessary 
In signed arithmetic we could end up with an i64 trip count for an i32 phi.
Because it is signed arithmetic we know that this is only defined if the i32
does not wrap. It is therefore safe to truncate the i64 trip count to a i32
value.

Fixes PR18049.
