[X86] Add test caes for opportunities for machine LICM to unfold broadcasted constant pool loads.

MachineLICM is able to unfold loads to move an invariant load out
a loop, but X86 infrastructure currently lacks the ability to do
this when avx512 embedded broadcasting is used.

This test adds examples for the basic float point operations,
add, mul, and, or, and xor.
