[ARM][tests] Make input and output arrays 128-bit aligned in vectorisation tests

	* gcc.target/arm/vect-lceilf_1.c: Make input and output arrays global
	and 16-byte aligned.
	* gcc.target/arm/vect-lfloorf_1.c: Likewise.
	* gcc.target/arm/vect-lroundf_1.c: Likewise.
	* gcc.target/arm/vect-rounding-btruncf.c: Likewise.
	* gcc.target/arm/vect-rounding-ceilf.c: Likewise.
	* gcc.target/arm/vect-rounding-floorf.c: Likewise.
	* gcc.target/arm/vect-rounding-roundf.c: Likewise.
