Improve ISel across lane float min/max reduction
In vectorized float min/max reduction code, the final "reduce" step
is sub-optimal. In AArch64, this change wll combine :
svn0 = vector_shuffle t0, undef<2,3,u,u>
fmin = fminnum t0,svn0
svn1 = vector_shuffle fmin, undef<1,u,u,u>
cc = setcc fmin, svn1, ole
n0 = extract_vector_elt cc, #0
n1 = extract_vector_elt fmin, #0
n2 = extract_vector_elt fmin, #1
result = select n0, n1,n2
into :
result = llvm.aarch64.neon.fminnmv t0
This change extends r247575.
