René Scharfe 9ca356fa8b coccinelle: remove parentheses that become unnecessary 
Transformations that hide multiplications can end up with an pair of
parentheses that is no longer needed.  E.g. with a rule like this:

  @@
  expression E;
  @@
  - E * 2
  + double(E)

... we might get a patch like this:

  -	x = (a + b) * 2;
  +	x = double((a + b));

Add a pair of parentheses to the preimage side of such rules.
Coccinelle will generate patches that remove them if they are present,
and it will still match expressions that lack them.
