Fix non-SIMD alignment if void* bigger than double When building without the SIMD extensions, memory allocations are currently aligned to sizeof(double). However, this may be insufficient on architectures such as Arm Morello or 64-bit CHERI-RISC-V where pointers require 16-byte rather than 8-byte alignment. This patch causes memory allocations to be aligned to MAX(sizeof(void *), sizeof(double)) when building without the SIMD extensions. (NOTE: With C11 we could instead use alignof(max_align_t), but C89 compatibility is still necessary in libjpeg-turbo.) Closes #587
