X-Git-Tag: go1.15beta1~757

cmd/link/internal/arm64: increase the function alignment to 16

On arm64, a function's address is 16 bytes aligned, and
the assembler aligns the size of function symbol to 16 bytes,
so to keep the consistent, this patch changes the function
alignment in the linker to 16 bytes.
