[PATCH] Fix -Wshadow=local warnings in rtl.h

Hi,

this fixes -Wshadow=local warnings in the RTL_FLAG_CHECKx macros,
which happen when this macro is used recursively in a macro
argument.  The __typeof (RTX) const _rtx in the inner macro
expansions shadows the outer macro expansions.

So reworked the macro to not use statement expressions but
use templates instead.  Since the 7-argument overload is not
used anywhere removed RTL_FLAG_CHECK7 for now.


Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?


Thanks
Bernd.
