Fix performance regression on processors that allow unaligned mem access. #30

Closed shumow closed 7 years ago

shumow commented 7 years ago

This fix detects architectures that support unaligned memory access and avoids a memory copy on such platforms. This holds on the x86-32 and -64 processors, which are a common use case.
