Correctly describe POPCNT compile SSE4.2 has nothing to do with POPCNT. We must dispell this myth, because Stockfish is a reference and many will copy this mistake if they see it in Stockfish: * SSE is an SIMD instruction set, relative to vectorization (using special 128-bit registers). * POPCNT/LZCNT work on normal registers (eg. AL, AX, EAX, RAX). The confusion comes from the fact that, in the Intel product line, it just so happens that SSE4.2 and POPCNT/LZCNT came out at the same time. But this is not true for AMD. For example, all AMD Pheniom II have SSE3 but no POPCNT/LZCNT, and that is why the modern compile uses -msse3 -popcnt and not -msse4.2. No functional change. Resolves #86
