Add a new test titled: Test x86 instruction decoder - new instructions The purpose of this test is to check the instruction decoder after new instructions have been added. Initially, MPX instructions are tested which are already supported, but the definitions in x86-opcode-map.txt will be tweaked in a subsequent patch, after which this test can be run to verify those changes. The data for the test comes from assembly language instructions in insn-x86-dat-src.c which is converted into bytes by the scripts gen-insn-x86-dat.sh and gen-insn-x86-dat.awk, and included into the test program insn-x86.c as insn-x86-dat-32.c and insn-x86-dat-64.c. The conversion is not done as part of the perf tools build because the test data must be under (git) change control in order for the test to be repeatably-correct. Also it may require a recent version of binutils.
