vim-patch:9.2.1101: modifier_len() scans the whole command modifier table

Problem:  modifier_len() always iterates every entry of cmdmod_info_tab[]
          when checking for a command modifier, even though the table is
          sorted by name; this runs for every sourced line via
          has_loop_cmd() and shows up when loading large syntax scripts.
Solution: Break out of the loop as soon as the table entry's first letter
          is past the command's first letter, since no later entry can
          match in a name-sorted table (Julien Voisin).

Adding an early break roughly halves the instruction count spent in
modifier_len() and shaves about 1.5% to 2% off single-file syntax load across
common filetypes, with no change in behaviour.
