bpf: correct pseudo-C template for add3 and sub3
The pseudo-C output templates for these instructions were incorrectly
using operand 1 rather than operand 2 on the RHS, which led to some
very incorrect assembly generation with -masm=pseudoc.
gcc/
* config/bpf/bpf.md (add<AM:mode>3): Use %w2 instead of %w1
in pseudo-C dialect output template.
(sub<AM:mode>3): Likewise.
gcc/testsuite/
* gcc.target/bpf/alu-2.c: New test.
* gcc.target/bpf/alu-pseudoc-2.c: Likewise.
