[PATCH] [arm][testsuite]: Fix ACLE data-intrinsics testcases

data-intrinsics-assembly.c forces -march=armv6 using dg-add-options arm_arch_v6, which implicitly adds -mfloat-abi=softfp. However, for a toolchain configured for arm-linux-gnueabihf and --with-arch=armv7-a, the testcase will fail when including arm_acle.h (which includes stdint.h, which will fail
