Clang is unable to handle the situation that a chunk of inline assembly ends with a compat branch instruction and then compiler generates another control transfer instruction immediately after this compat branch. The later instruction will end up in forbidden slot and cause exception. Workaround by add a option to control the use of compact branch. Currently it's selected by CC_IS_CLANG and hopefully we can change it to a version check in future if clang manages to fix it. Fix boot on boston board.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
