And removes i686 support now that CET is x86_64 only.  It essentially
removes the i386 support from:

  - faaee1f07ed (x86: Support shadow stack pointer in setjmp/longjmp).
  - be9ccd27c09 (i386: Add _CET_ENDBR to indirect jump targets in)
    add_n.S/sub_n.S).
  - faaee1f07ed (x86: Support shadow stack pointer in setjmp/longjmp).
  - c02695d7764 (x86/CET: Update vfork to prevent child return).
  - c02695d7764 (x86: Update vfork to pop shadow stack).

And move the Makefile and tests from the generic x86 folder to x86_64
one.

The --enable-cet now issues an error with i686-linux-gnu.

Checked on x86_64-linux-gnu and i686-linux-gnu.

Can you break it into 2 parts:

1. Move x86 CET files to x86_64.
2. Remove CET support from i386 files.

Thanks.
