Fix SSE detection on non-AVX CPUs (#135)

Browse Source 
Fixes #4. This is based on #115 with a few modifications:
 - Removed use of __builtin_cpu_supports since it relies on cpuid and doesn't improve on the current situation,
 - Added detection for all of sse, sse2, sse3, ssse3, sse4_1 and sse4_2,
 - Added tests for Atom, Nehalem, and P3 processors,

Thx to @gadoofou87 for providing the original PR.
It also removes the need for #92
