The apple,nclusters property is a remnant of early bringup and never made
it in the official bindings. Drop it and calculate the number of clusters
from the register area size. Fixes out-of-bounds access on SoCs that
provide less than 6 clusters.

editors/openoffice-4: Upgrade to 4.1.17 RC1
Upgrade Apache OpenOffice to version 4.1.17 RC1.
Switch from system textproc/libtextcat to bundled libtextcat.
The system version probably never worked properly because it
lacks UTF-8 support, whereas the bundled version has been patched
to support UTF-8. Regenerate the libtextcat patch from the
version on the trunk branch which has FreeBSD build fixes.
Longer term, libtextcat should be replaced by libexttextcat.
Disable WIKI_PUBLISHER and mark BROKEN. It relies on
apache-commons-httpclient which has an open MITM CVE. It should
be upgraded to Apache HttpComponents, but that requires a newer
java.
Remove old code optimization tweak that is probably left over
from when we used the buggy -Os compiler optimization flag.

linux(4): Fix signal mask restoration in epoll_pwait(2)/epoll_pwait2(2)
Since 80c7315d17ce ("Restore signal mask in epoll_pwait.") the caller's
signal mask is saved in a local variable, but TDP_OLDMASK is still set
and the TDA_SIGSUSPEND AST is still scheduled. On return to user mode
that AST, or postsig() if a signal is delivered, then installs
td_oldsigmask, which this code never writes and which holds whatever
mask the thread had at its last sigsuspend(2), pselect(2) or ppoll(2).
As a result every epoll_pwait(2)/epoll_pwait2(2) call with a non-NULL
sigmask can leave the thread with a stale signal mask. In addition, the
explicit restore at the end overwrote the return value, so EINTR (and
any other error) was reported to user space as 0.
Save the old mask in td_oldsigmask and let the AST restore it, as
kern_pselect() and kern_poll_kfds() do: schedule TDA_SIGSUSPEND if the
wait was interrupted, so the signal is delivered with the temporary mask
in place, and TDA_PSELECT otherwise. This matches Linux, which restores
the saved mask unless the syscall returns -EINTR.

[DenseMap] Share rehash and grow for relocatable bucket types. NFC (#225018)
DenseMap is heavily instantiated and moveFrom and grow are among the
largest code families. For trivially copy constructible and destructible
bucket types (also satisfied by std::pair), call an out-of-line
`growRelocatable` with size/align/hasher (dictionary passing style).
A pointer key hashed by its value hashes inline, which a null
BucketHasher asks for, sparing a call per entry.
DenseMapInfo<T *>::PointerValueHash names the class declaring it, so an
info that specializes or inherits it to hash the pointee -- Attributor's
InstExclusionSet, VPCSEDenseMapInfo, MachineInstrExpressionTrait --
keeps its own hash. Any other key hashes through a thunk, one per
(KeyT, KeyInfoT) whatever the map's value type.
SmallDenseMap's in-place rehash for remove_if shares the loop through
`rehashRelocatable`. It rehashes once rather than into a temporary map
and back, which can reorder a probe chain that wraps around the table.

[IR] Memory effects for floating-point operations
Floating-point operations in a strictfp function have side effects,
which are modeled using memory effects in the form of a read-write
access to "inaccessible memory". This helps maintain strictfp semantics
but may hinder optimizations. Floating-point operations may depend on
rounding mode or not - this fact may be used to reorder them in a more
optimal way. Similarly, functions that control floating-point
environment (like `set_rounding`, `set_fpmode` etc.) also have more
specific access than generic read-write. Also, "inaccessible memory" is
used in cases other than FP operation, this results in unnecessary
restrictions.
This change implements two new memory location to use instead of the
access to "inaccessible memory". The "fpcontrol" location is used to
represent access to floating-point control modes, of which only rounding
mode is currently supported. The other location, "fpstatus", represents
access to floating-point exceptions. Together they replace the use of
"inaccessible memory".

[libc++][AIX] Add system library path via blibpath for lldb (#223837)
On AIX some tools we use for testing libc++, like lldb, are linked
against the system libc++, which has additional members (e.g
`shr2_64.o`) that the newly built libc++.a doesn't have. But the current
test harness set the `LIBPATH` to point at the newly built libc++, which
can load break these tools.
This change removes the `LIBPATH` and instead sets the `blibpath`
(equivalent to rpath on other systems), which helps lldb find the system
libc++.a, while still running the tests against the libc++ build under
test.
