  -----------
  [Verifier] Allow vector type in atomic load and store

Vector types on atomics are assumed to be invalid by the verifier. However,
this type can be valid if it is lowered by codegen.

  Log Message:
  -----------
  [SelectionDAG][X86] Add floating point promotion.

When lowering atomic vector types with floats, selection can fail since
this pattern is unsupported. To support this, floats can be casted to
an integer type of the same size.

Atomic vectors with size >1 are lowered to calls. Adding
their tests separately here.
