final: Improve output for -dp and -fverbose-asm
This improves the assembler output (for -dp and -fverbose-asm) in
several ways. It always prints the insn_cost. It does not print
"[length = NN]" but "[c=NN l=NN]", to save space. It does not add one
to the instruction alternative number (everything else starts counting
those at 0, too). And finally, it tries to keep things lined up in
columns a bit better.
* final.c (output_asm_name): Print insn_cost. Shorten output. Print
which_alternative instead of which_alternative + 1.
(output_asm_insn): Print an extra tab if the template is short.
