[testsuite] Run more gcc.dg/store_merging_*.c tests

[Eric Botcazou]

There is a handful of gcc.dg/store_merging_*.c tests in the testsuite with 
both a main procedure doing sanity checks and a dg-do compile directive.

Tested on x86-64/Linux, applied on the mainline and 8 branch as obvious.

        * gcc.dg/store_merging_10.c: Turn dg-do compile into dg-do run.
        * gcc.dg/store_merging_11.c: Likewise.
        * gcc.dg/store_merging_13.c: Likewise.
        * gcc.dg/store_merging_14.c: Likewise.
        * gcc.dg/store_merging_15.c: Likewise.
        * gcc.dg/store_merging_16.c: Likewise.  Remove local variable.
