Michael Kuperstein 5185b7dde3 [LV] Remove triples from target-independent vectorizer tests. NFC. 
Vectorizer tests in the target-independent directory should not have a target
triple. If a test really needs to query a specific backend, it belongs in the
right target subdirectory (which "REQUIRES" the right backend). Otherwise, it
should not specify a triple.

Wei Mi edae87d819 The patch replace the overflow check in loop vectorization with the minimum loop iterations check. 
The loop minimum iterations check below ensures the loop has enough trip count so the generated
vector loop will likely be executed, and it covers the overflow check.

Differential Revision: http://reviews.llvm.org/D12107.
