Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

makes it easier to build head on stable/9, where libstdc++ is still the
default. We can revisit this when somebody will try to build base with
gcc 4.8.1 or higher, and its included libstdc++.

[X86] Convert esp-relative movs of function arguments to pushes, step 2
This moves the transformation introduced in r223757 into a separate MI pass.
This allows it to cover many more cases (not only cases where there must be a
reserved call frame), and perform rudimentary call folding. It still doesn't
have a heuristic, so it is enabled only for optsize/minsize, with stack
alignment <= 8, where it ought to be a fairly clear win.

This helps to get sys/boot/i386/boot2 below the required size again,
when optimizing with -Oz.
these in $LIBDIR/clang/$VERSION/include, instead of our previous custom
location in /usr/include/clang/$VERSION. This allows us to drop yet
another FreeBSD-specific patch.
to ease any rework of how clang is built to take arm64 in to account.

the oabi is still in the tree, but it is expected this will be removed
as developers work on surrounding code.
With this commit the ARM EABI is the only supported supported ABI by
FreeBSD on ARMa 32-bit processors.

source files could be passed to tblgen or clang-tblgen, leading to a
"Too many positional arguments specified" error message. Fix this by
replacing the too-generic ${.ALLSRC} sources with explicit paths.
