## Detailed Description

SSE2 reinitialization guard class.

SSE2 requires to call _mm_empty() if we are intermixing MMX integer commands with floating point arithmetics. This class guards critical code fragments where SSE2 integer is used.

As of 2015 _mm_empty() is considered deprecated, and not even recognised by some compilers (like MSVC) in 64-bit mode. As MMX instructions gets old, we here deprecate and comment out use of _mm_empty()
