For example, the following transformation:
- sizeof(s)-1
+ STRLEN(s)
would replace sizeof by STRLEN even in the STRLEN macro definition
itself, which generates following nonsensical patch:
--- src/basic/macro.h

@@ -182,7 +182,7 @@ static inline unsigned long ALIGN_POWER2

-#define STRLEN(x) (sizeof(""x"") - 1)
+#define STRLEN(x) (STRLEN("" x ""))
/*

Let's exclude the macro itself from the transformation to avoid this
This makes things a bit easier to read I think, and also makes sure we
always use the _unlikely_ wrapper around it, which so far we used
sometimes and other times we didn't. Let's clean that up.
