x86, perf: Add a build-time sanity test to the x86 decoder
Add a sanity test of x86 insn decoder against a stream
of randomly generated input, at build time.
This test is also able to reproduce any bug that might
trigger by allowing the passing of random-seed and
iteration-number to the test, or by passing input
which has invalid byte code.
Changes in V2:
- Code cleanup.
- Show how to reproduce the error by insn_sanity test.
