[InstCombine] Fold lshr 1, X into zext (X == 0) (#200669)
This PR implements the missed optimisation reported in #200538.
`1 >> X` produces 1 only when X == 0, and 0 for all other in-range
values. Fold it directly into `zext (icmp eq X, 0)`.
[AArch64][SME] Add multi-vector load opcodes to getMemOpInfo (#200238)
We recently started emitting these in
84fab943b5740ec273e9f8d238ea8420033320a4, which now means we can hit an
unhandled opcode error in AArch64InstrInfo::getMemOpInfo when resolving
stack offsets.
Fixes #200034
[M68k][MC] Add MC support for PCI w/ base displacement addressing mode (#200696)
Program Counter Indirect with Index (PCI) is augmented in M68020+ with
(1) larger displacement (up to 32-bit), and (2) Index scaling factor. We
call this PCIBD (PCI with Base Displacement) to distinguish it with the
older PCI.
Since all the components inside PCIBD are optional, including index
register, we can actually use it to replace PCD (PC displacement)
addressing mode in newer machines in order to leverage the larger
displacement.
This is the first step to support 32-bit memory addresses on M68020+
machines.
[AArch64][SVE] Handle multi-vector load/store opcodes in frame-index elimination
Lowering a wide scalable load from a stack object produces an
LD1*_{2Z,4Z}_IMM[_PSEUDO] with a frame-index base. getMemOpInfo() and getLoadStoreImmIdx()
had no entries for these SME2/SVE2p1 multi-vector opcodes, so PEI crasheds.
When pane-border-indicators is set to "both" or "arrows", only draw
arrows on the active floating pane and no other floating panes. Also
there is no need to loop in screen_redraw_cell_border if only checking
one pane.

devel/mate-common: switch to GitHub release asset
Minor versions of 1.28.x are no longer published to the MATE mirror
and are only available on GitHub. Use USE_GITHUB=nodefault with a
release tarball instead of the auto-generated one, as recommended
by the porter's handbook. Remove autoreconf, not needed with release
tarballs.
Fix vmd(8) emulation for Linux guests.
The memory safety checks introduced in previous commit were too
strict and broke Linux guests running on top of vmd. Adapt the
checks to the variation of virtio 1.x that vmd implements.
virtio 1.x doesn't need page alignment. The used area offset needs
to just be 4 byte aligned for some sanity, but not really critical.
The descriptor table, available area, and used areas must be in
guest memory ranges and not spill out allowing guest access to host
memory by using hvaddr_mem() to check.

[ARM] Fix some fp16 Shuffle lowering without +fullfp16 (#200688)
Without fullfp16 f16 is not a legal type, meaning we need to be careful
with
how we legalize shuffle vector and buildvector operations that cannot be
treated more optimially using shuffles.
