PR target/102785: Correct addsub/subadd patterns on bfin.
This patch resolves PR target/102785 where my recent patch to constant
fold saturating addition/subtraction exposed a latent bug in the bfin
backend. The patterns used for blackfin's V2HI ssaddsub and sssubadd
instructions had the indices/operations swapped. This was harmless
until we started evaluating these expressions at compile-time, when
the mismatch was caught by the testsuite.
