David Laight 598f0ac150 compiler.h: move __is_constexpr() to compiler.h 
Prior to f747e6667e __is_constexpr() was in its only user minmax.h. 
That commit moved it to const.h - but that file just defines ULL(x) and
UL(x) so that constants can be defined for .S and .c files.

So apart from the word 'const' it wasn't really a good location.  Instead
move the definition to compiler.h just before the similar

  is_signed_type() and is_unsigned_type().

This may not be a good long-term home, but the three definitions belong
together.

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.
