David Sherwood d581d94385 [SVE] Fix the FP arithmetic instruction costs for SVE ...

Several FP instructions (fadd, fsub, etc.) were incorrectly assigned
a higher cost for SVE because they have custom lowering, however we
know they are legal. This patch explicitly assigns a cost of 2 to
these opcodes.
