[AArch64][ELF] Section alignment of 4 for AArch64 instruction

The integrated assembler sets a minimum alignment for the .text section of 4. However user defined sections get an alignment of 1. Unlike the GNU assembler which raises the section alignment to 4 if an AArch64 instruction is used, the integrated assembler leaves the alignment at 1
