Changes

Summary

1. [X86] Pull out repeated Subtarget feature tests. NFCI. Avoids a scan-build "uninitialized value" warning in X86FastISel::X86SelectFPExtOrFPTrunc
2. [TargetLowering] getValueType - use dyn_cast directly to find VectorType. NFCI. Matches what we do in other getValueType functions and fixes a null dereference warning in scan-build. Also cleans up the rest of the function - use auto and standardize the variable names.
