Benjamin Kramer dc145816fd LoopVectorize: Vectorize math builtin calls. 
This properly asks TargetLibraryInfo if a call is available and if it is, it
can be translated into the corresponding LLVM builtin. We don't vectorize sqrt()
yet because I'm not sure about the semantics for negative numbers. The other
intrinsic should be exact equivalents to the libm functions.

Nadav Rotem 30a65bc39e Remove the -licm pass from the loop vectorizer test because the loop vectorizer does it now.

Nadav Rotem 6d9dafe3ff Force a fixed unroll count on the target independent tests. 
This should fix clang-native-arm-cortex-a9. Thanks Renato.

Paul Redmond 2adb13c100 LoopVectorize: support vectorizing intrinsic calls 
- added function to VectorTargetTransformInfo to query cost of intrinsics
- vectorize trivially vectorizable intrinsic calls such as sin, cos, log, etc.
