The official list of dependency-breaking instructions from Section 3.5.1.6 of
the Intel 64 and IA-32 Architectures Optimization Reference Manual (i.e., the
ones with hardware support in the out-of-order execution engine) is:

xor reg,reg
sub reg,reg
xorps/pd xmmreg,xmmreg
pxor xmmreg,xmmreg
subps/pd xmmreg,xmmreg
psubb/w/d/q xmmreg,xmmreg
