Subject: [PATCH] [X86] load atomic vector tests for combine
Vector types of 2 elements that don't require widening are lowered
via the prior commit's combine method, which is also needed to avoid
a vector move. This change adds the tests that depend strictly on
combineAtomicLoad so that SelectionDAG can translate vectors
with type bfloat,half.
