Add support for line numbers in copy mode. A new copy-mode-line-numbers
option has the following modes: off, default (tmux's normal line
numbering where 0 is the top visible line), absolute (first line in
history is 1), relative (relative to the cursor) and hybrid (current
line is absolute, others relative). Also adds
copy-mode-line-number-style and copy-mode-current-line-number-style to
set the style of the line numbers. When copy mode is entered with the
mouse, line numbers stay off.

[AArch64][DAG] Copy flags when narrowExtractedVectorBinOp-ing
The `extract (binop B0, B1), N` fold above already copies flags, use the same for
the `extract (binop (concat X1, X2), Y), N` version. In this case it is helping
copy disjoint or flags.
[AArch64] Use add_like for UMLAL / SMLAL (#194139)
Similar to the others, this allows us to generate UMLAL and SMLAL from
add-like disjoint ors. There are some cases where we lose the disjoint
from the or, those are being fixed separately (#193446).
[LV] Use isLegalMaskedLoadOrStore for interleaved accesses too (NFC)
isLegalMaskedLoadOrStore is now the central place for querying target
capabilities for masked accesses. Access pattern legality checks are
hoisted outside of it.
[LV] Introduce isLegalMaskedLoadOrStore (NFC)
This simplifies legality checks, and eventually will become the single
point querying TTI hooks for masked ld/st. Currently, legality checks
for interleaved accesses still query TTI directly.
