Author: Dale Curtis <dalecurtis@chromium.org>

    Apply deterministic build patch.

    This removes __DATE__ from a few places to ensure the build is always
    the same. Patch originally authored by davidben at chromium.org

    This is one of the initial commits preparing NASM for use in Chrome.

    Fix extern_inline for MSVC and clang-cl

    Prior to this change, no inline function bodies would be provided for
    MSVC. This change fixes that, so nasm will be slightly faster.

    With clang-cl, however, there would be LNK4006 warnings if the compiler
    chooses not to inline the ilog2 functions. The easiest way to observe
    this is with `nmake /f Mkfiles/msvc.mak CC=clang-cl DEBUG=1`. This
    disables inlining, and I see this at the end of the link:
      ilog2.obj : warning LNK4006: ilog2_32 already defined in outmacho.obj; second definition ignored
      ilog2.obj : warning LNK4006: ilog2_64 already defined in eval.obj; second definition ignored
      ilog2.obj : warning LNK4006: alignlog2_32 already defined in outmacho.obj; second definition ignored

    When additional instrumentation (-fprofile-instr-generate) is enabled,
    the warning can become an error, as we discovered in
    https://crbug.com/989745.

    MSVC and compilers pretending to be MSVC (clang-cl) implement inline in
    C with C++ semantics. In C++, inline functions are emitted by the
    compiler whenever they are needed and the linker discards duplicate
    inline function definitions. This change adds a new HAVE_MSVC_INLINE
    macro and adjusts the ifdefs to handle this mode. I chose to keep
    ilog2.c as part of the build, and to have it emit duplicate definitions
    of all the inline functions. An alternative solution would be to exclude
    it from the build, but I felt it was best to solve this in source code
    instead of the build system.

    Chromium-specific: I reran find_patches.py with some modifications to
    make it work on Windows.

    BR 3392692: outcoff: allow user to reduce the default alignment

    NASM would incorrectly only allow for the alignment to be increased,
    even when overridden by the user. Allow the user to specify any
    alignment value and have it override the partition type default.

    The user can increade their own alignment value specification later,
    of course, and the sectalign directive will present a floor for either
    kind of specification.
