[PATCH] Make 'symbol-file' not care about the position of command line arguments

[Sergio Durigan Junior <sergiodj at redhat dot com>]

This is a bug that's been detected while doing the readnever work.
Currently if you use the 'symbol-file' command you have to be careful
about the position of each argument you pass on the command line.
This is because while parsing its arguments, if the command detects a
filename, it promptly calls 'symbol_file_add_main_1' without waiting
to see if there are other args on the line.  This only affects the
'-readnow' argument so far, but while implementing the '-readnever'
command it also affected it.

gdb/ChangeLog:

2017-11-29  Sergio Durigan Junior  <sergiodj@redhat.com>

	* symfile.c (symbol_file_command): Call
          'symbol_file_add_main_1' only after processing all command
          line options.
