This commit add support for more atomic operations and type. The operations added are logical and, logical or, logical xor, swap, min, and max. New types are 32-bit int by using the MCA_BTL_ATOMIC_FLAG_32BIT flag, 64-bit float by using the MCA_BTL_ATOMIC_FLAG_FLOAT flag, and 32-bit float by using both flags. Floating point numbers are supported by packing the number in as an int64_t or int32_t. We will update the btl interface in the future to make this less confusing.

This commit fixes a programming error when using an aries nic. The documentation of ugni shows that only the local alignment restriction for get was lifted on aries. There is still a remote address alignment restriction. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
