Add two missing style checks for token spacing for binary operators when
switches -gnatyt, -gnatyy or -gnatyg is used.
Preserve previous behavior with debug switch -gnatd.Q

Test:
$ gcc -c pkg.ads -gnatyt -gnatl -gnatd7

Compiling: pkg.ads

     1. package Pkg is
     2.    One : constant := 1;
     3.    type Entier is range 0 .. 16-One;
                                       |
        >>> (style) space required

     4.    AB : constant String := "A"&"B";
                                      |
        >>> (style) space required

     5. end Pkg;

 5 lines: No errors, 2 warnings

Invoking
   gcc -c pkg.ads -gnatyt -gnatd.Q
should not report any warning.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* par-ch4.adb (Simple_Expression): Add missing style check
	for binary adding operators.
	(Term): Add missing style check for multiplying operators.
