arm: improve tests for vld2q*

gcc/testsuite/ChangeLog:

	* gcc.target/arm/mve/intrinsics/vld2q_f16.c: Use
	check-function-bodies instead of scan-assembler checks.  Use
	extern "C" for C++ testing.
	* gcc.target/arm/mve/intrinsics/vld2q_f32.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vld2q_s16.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vld2q_s32.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vld2q_s8.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vld2q_u16.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vld2q_u32.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vld2q_u8.c: Likewise.
