This patch (also applicable to trunk) makes us canoncialize operand
order for comparisons at the same time we canonicalize other
operand order, in particular before dispatching to generic_simplify.
It also adds operand canonicalization to ternary ops and adds
FMA_EXPR and DOT_PROD_EXPR to the list of ternary commutative ops.
Bootstrap and regtest running on match-and-simplify branch and
x86_64-unknown-linux-gnu.

* fold-const.c (fold_comparison): Remove redundant constant
folding and operand swapping.
(fold_binary_loc): Do comparison operand swapping here,
dispatch to generic_simplify after operand canonicalization.
(fold_ternary_loc): Canonicalize operand order for
commutative ternary operations.
* tree.c (commutative_ternary_tree_code): Add DOT_PROD_EXPR
and FMA_EXPR.
Seems like something we'd want for the trunk independent of the
match-and-simplify work
