0b57cec536 Move all sources from the llvm project into contrib/llvm-project.
This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo".  That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

1fa29c42bb Fix LLVM libunwnwind _Unwind_Backtrace symbol version for ARM.
In original  GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 version

version. This was originally omitted in r255095, fixed in r318024 and omitted
aging in LLVM libunwind implementation in r354347.

For ARM _Unwind_Backtrace should be published as default with GCC_4.3.0
version , (because this is right original version) and again as
normal(not-default) with GCC_3.3 version (to maintain ABI compatibility
compiled/linked with wrong pre r318024 libgcc)

c62ff2800b Deprecate sranddev(3) API
It serves no useful purpose and wasn't as popular as its equally meritless
cousin, srandomdev(3).

Setting aside the problems with rand(3) in general, the problem with this
interface is that the seed isn't shared with the caller (other than by
attacking the output of the generator, which is trivial, but not a hallmark of
pleasant API design).  The (arguable) utility of rand(3) or random(3) is as a
semi-fast simulation generator which produces consistent results from a given
seed.  These are mutually at odd.  Furthermore, sometimes people got the
mistaken impression that a high quality random seed meant a weak generator like
rand(3) or random(3) could be used for things like cryptographic key
generation.  This is absolutely not so.

The API was never part of a standard and was not widely used in tree.  Existing
in-tree uses have all been removed.

Possible replacement in out of tree codebases:

	char buf[3];
	time_t t;

	time(t);
	strftime(buf, sizeof(buf), "%S", gmtime(&t));
	srand(atoi(buf));

59e1870182 [PowerPC] Fully define gdtoa settings on powerpc64.
The settings in arith.h were not fully defined on powerpc64 after the gdtoa
switchover. Generate them using arithchk.c, similar to what AMD64 did for
r114814.

Technically, none of this is necessary in FreeBSD gdtoa, but since the other
platforms have full definitions, we might as well have full definitions
too.

This is the half of the changes required that work as-is with both in-tree
ZFS and the new hotness, sysutils/openzfs.  Highlights are less dependency
on header pollution (from somewhere) and using 'mnttab' instead of
'extmnttab'.   In the in-tree ZFS, the latter is a #define for the former,
but in the port extmnttab is actually a distinct struct that's a super-set
of mnttab.  We really want mnttab here anyways, so just use it.

adc56f5a38 Make use of the stats(3) framework in the TCP stack.
This makes it possible to retrieve per-connection statistical
information such as the receive window size, RTT, or goodput,
using a newly added TCP_STATS getsockopt(3) option, and extract
them using the stats_voistat_fetch(3) API.

See the net/tcprtt port for an example consumer of this API.

Compared to the existing TCP_INFO system, the main differences
are that this mechanism is easy to extend without breaking ABI,
and provides statistical information instead of raw "snapshots"
of values at a given point in time.  stats(3) is more generic
and can be used in both userland and the kernel.

83fa0a287f The fdlibm hypot() implementations shouldn't potentially left-shift
negative numbers (invoking undefined behavior)

Summary:
Various paths through hypot(x, y) will multiply x and y by a power of
two, perform the calculation in a range where IEEE-754 provides greater
precision, then undo the multiplication to determine the true result.
Undoing that multiplication is implemented as t1*w, where t1=2**k.

2**k is often computed by taking the high word of 1.0, then adding k<<20
(for doubles or long doubles) or k<<23 (for floats) to it, then
overwriting that high word. But when k is negative this left-shifts a
negative value -- and that's undefined behavior in many editions of C
and C++.

This patch should fix all hypot implementations to compute 2**k without
triggering this particular bit of undefined behavior.

Test Plan: I've only very lightly tested out the hypot(double, double)
change, in SpiderMonkey's JavaScript engine, for consistency with prior
behavior.  The other functions' changes have more or less only been
eyeballed.  Careful examination appreciated!  Do note, however, that an
error in any of these changes would most likely produce a value that is
incorrect by a factor of two, so any mistake would most likely be
glaring if invoked.
