[GlobalISel] Add or_and_and pattern from SelectionDAG (#204618)
This PR adds the `fold or (xor x, y), (x and/or y) --> or x, y` pattern
from SelectionDAG to GlobalISel.
[CodeGen][NFC] Store CPU model index in SubTypeKV (#207351)
Instead of storing the pointer to the CPU model, store all CPU models in
an array and store the index. This is preliminary work for moving
SubTypeKV to .rodata.
NB: the scheduling models also take a fair amount of space in
.data.rel.ro, with SchedModels ~13kiB, ModelProcResources ~57kiB.
[GenericDomTreeConstruction] Use 0-based DFS numbering (#207524)
Number DFS-visited nodes from 0 and drop the unused index-0 sentinel
from NumToNode/NumToInfo/IDoms.
`Unvisited = 0` marks unvisited nodes by DFS. 0 is now the DFS root, or
the virtual root for postdominators.
Decrease the inline capacity for NumToNode/NodeInfos, which doesn't seem
to matter. sqlite3's p90 block count is 29.
[libc++] Mark LWG4098 as resolved (#206295)
Already implemented and tested in the scope of the full implementation
for `adjacent_view` (1e15dbe311eb08462e7a68fcb8b5850632e24aff).
Closes #105353

libsysdecode: cache Generic Netlink family IDs
Record Generic Netlink family IDs learned from
CTRL_CMD_GETFAMILY responses and use them to decode subsequent
Generic Netlink messages using symbolic family names instead of
numeric IDs.

truss: track Netlink socket protocols
Record the Netlink protocol associated with AF_NETLINK sockets when
they are created and pass it to libsysdecode during message decoding.
Use the protocol to distinguish between Generic Netlink and Route
Netlink sockets, ensuring that Generic Netlink decoding is only
performed for NETLINK_GENERIC sockets.

Make sysinst intercept kernel console messages using TIOCCONS at all
times, not just when running an external command, and discard those
that occur when not running an external command so that they don't
mess up the display when running sysinst on the console. Fixes
PR install/54932.
