Assorted testsuite fixes

First, gcc.dg/array-quals-1.c does not pass if the compiler is configured
with --enable-default-pie because the sections change, so force -fno-pie.
Second, replace *-*-solaris* with sparc*-*-* for gfortran.dg/pr95690.f90
because this depends on the architecture rather than the OS.  Third force
SRA to trigger on Aarch64 (like PowerPC) for gnat.dg/opt39.adb.

gcc/testsuite/
	* gcc.dg/array-quals-1.c: Pass -fno-pie if supported.
	* gcc.dg/loop-9.c: Likewise.
	* gfortran.dg/pr95690.f90: Replace *-*-solaris* with sparc*-*-*.
	* gnat.dg/opt39.adb: Pass --param option for Aarch64 too.
