[Kim Barrett]

> Please review this change to eliminate some -Wparentheses warnings. This
> involved simply adding a few parentheses to make some implicit operator
> precedence explicit.
> 
> This change addresses non-C2 parts of the compiler component.
> 
> Testing: mach5 tier1
> 
> Also ran mach5 tier1 with these changes in conjunction enabling -Wparentheses
> and other changes needed to make that work.
