Subject: [PATCH] FixIt: use getLocForEndOfToken to insert fix-it after a type
 name.

Instead of setting DeclSpec's range end to point to the next token
after the DeclSpec, we use getLocForEndOfToken to insert fix-it after a type
name.

Before this fix, fix-it will change
^(NSView view) to ^(*NSView view)

This commit correctly updates the source to ^(NSView* view).
