re PR libfortran/38199 (missed optimization: I/O performance)

PR libfortran/38199
* io/read.c (read_decimal): Quickly skip spaces to avoid calls
to next_char.
* io/unit.c (is_trim_ok): New helper function to check various
conditions to see if its OK to trim the internal unit string.
(get_internal_unit): Use LEN_TRIM to shorten selected internal
unit strings for optimizing READ. Enable this optimization for
formatted READ.
* io/list_read.c (finish_list_read): Don't call eat_line for
internal units.
