This version 3 of the patch adds endianness safety to both the optimizations
brought by the patch set.
It also adds some conditions that allow the __builtin_memcpy to be executed
on chunks of 16 bytes with guarantee of atomicity.
Changes from V2:
- patch 1:
- add condition for the host not to be big endian.
- patch 2:
- add condition for the host not to be big endian.
- add condition for the host to support 16-byte atomic memory operations.
- limit the large loads and stores to 16 byte chunks in order to guarantee
atomicity on a larger range of processors.
