https://bugs.openjdk.java.net/browse/JDK-8198251
Graal's matcher does not support matching set of nodes into one x64 BMI
instruction how C2 does:
match(Set dst (AndI (XorI src1 minus_1) (LoadI src2)));
andnl($dst$$Register, $src1$$Register, $src2$$Address);
BMI tests should be excluded from Graal JIT testing for now.
We will file RFE for Graal to support such matching.
