seq(1, 10) should throw seq_linter()

[MichaelChirico]

          That's not the only case in mind for `seq_linter()`:

microbenchmark(times=100, seq(1, 1e7), seq_len(1e7))
# Unit: nanoseconds
#            expr  min   lq     mean median     uq    max neval cld
#   seq(1, 1e+07) 3640 3706 10314.14 3771.0 3901.0 633721   100   a
#  seq_len(1e+07)  121  150   862.12  161.5  220.5  67561   100   a

(I guess we don't cover that yet, but we should...)

This is somewhat a duplicate of #1927; including its own issue for emphasis given the above finding re: inefficiency of seq() for this case
