Add -funroll-loops to CXXFLAGS Optimize profiling data accuracy by enabling -funroll-loops during the profile generation phase, in addition to its default activation by -fprofile-use. This seems to produce a slightly faster binary, for most compilers. make -j profile-build ARCH=x86-64-avx2 sf_base = 1392875 +/- 5905 (95%) sf_test = 1402332 +/- 7303 (95%) diff = 9457 +/- 4413 (95%) speedup = 0.67896% +/- 0.317% (95%) STC: LLR: 2.93 (-2.94,2.94) <0.00,2.00> Total: 34784 W: 8970 L: 8665 D: 17149 Ptnml(0-2): 115, 3730, 9405, 4019, 123 https://tests.stockfishchess.org/tests/view/64d944815b17f7c21c0e92e1 closes https://github.com/official-stockfish/Stockfish/pull/4750 No functional change
