target-mips: Restore the order of helpers
Restore the order of helpers that used to be: unary operations (generic, then MIPS-specific), binary operations (generic, then MIPS-specific), compare operations. At one point FMA operations were inserted at a random place in the file, disregarding the preexisting order, and later on even more operations sprinkled across the file. Revert the mess by moving FMA operations to a new ternary class inserted after the binary class and move the misplaced unary and binary operations to where they belong. Signed-off-by: Maciej W. Rozycki <macro@codesourcery.com> Signed-off-by: Leon Alrae <leon.alrae@imgtec.com>
