[PATCH] Compile pr79793-[12].c with -mtune=generic

2017-07-31 Thread H.J. Lu 
pr79793-1.c and pr79793-2.c are failed when GCC is configured with
--with-cpu=slm since lea is used to adjust stack, instead of sub/add.
This patch uses -mtune=generic to always generate sub and add.

OK for trunk?

H.J.

* gcc.target/i386/pr79793-1.c: Compile with -mtune=generic.
* gcc.target/i386/pr79793-2.c: Likewise.
