[InstCombine] add folds for minnum(-a, -b) --> -maxnum(a, b)
...
This is similar to what we do for integer min/max with 'not'
ops (rL321882).
This should fix:

Fix using wrong intrinsic in test
...
This is a leftover from renaming the intrinsic.
It's surprising the unknown llvm. intrinsic wasn't rejected.

Add minnum / maxnum intrinsics
...
These are named following the IEEE-754 names for these
functions, rather than the libm fmin / fmax to avoid
possible ambiguities. Some languages may implement something
resembling fmin / fmax which return NaN if either operand is
to propagate errors. These implement the IEEE-754 semantics
of returning the other operand if either is a NaN representing
missing data.
