Fix arch/x86/tools/Makefile to compile both test tools
correctly. This bug leads build error.

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.

Check objdump version before using it for insn decoder build test,
because some older objdump can't decode AVX code correctly.

Fix postest_verbose to posttest_verbose, and add posttest_64bit option
for CONFIG_64BIT != y, since old command just passed '-' instead
of '-n' when CONFIG_64BIT is not set.

Add verbose option to insn decoder test. This dumps decoded
instruction when building kernel with V=1.

Add the kernel source include file as well to the include files
search path, to fix this build bug:

Pass $(CONFIG_64BIT) to the x86 insn decoder selftest in case we are
decoding 32bit code on x86-64, which will happen when building kernel
with ARCH=i386 on x86-64.

Fix x86 instruction decoder selftest to check only .text because other
sections (e.g. .notes) will have random bytes which don't need to be
checked.

Add a user-space selftest of x86 instruction decoder at kernel build
time.
When CONFIG_X86_DECODER_SELFTEST=y, Kbuild builds a test harness of x86
instruction decoder and performs it after building vmlinux.
The test compares the results of objdump and x86 instruction decoder
code and check there are no differences.
