[MachineCombiner] Defer pattern order verfication. NFC (#177081)
The `verifyPatternOrder` function was created to check if machine
combiner patterns are ordered by their latency reduction degree. This
function can be merged into the following loop, which iterates through
all the patterns, such that (1) `TII::genAlternativeCodeSequence`, which
can be quite expensive, won't be called twice (2) since it's now placed
after we print out the candidate sequence through debug print, if
anything goes wrong during the verification, we at least know what the
sequence looks like (3) we don't need to verify all patterns if we will
eventually exit early.
This should be a NFC

cron: Implement full PAM session lifecycle for user jobs
Extend PAM integration beyond account checks to include credential
establishment and session management, allowing PAM modules to configure
the execution environment for user cron jobs.
Previously, cron only called pam_acct_mgmt() to verify account validity
but immediately terminated the PAM handle before job execution. This
prevented PAM modules from establishing sessions, setting credentials
(e.g., Kerberos tickets), or exporting environment variables needed by
jobs.
The PAM handle now persists in the intermediate process throughout the
job execution, enabling proper session open/close pairing. Credentials
are established and sessions opened while still running as root, before
dropping privileges in the grandchild. PAM environment variables are
exported in the job process with user crontab variables taking precedence.
A session rule (pam_permit.so) is added to /etc/pam.d/cron to enable

[LoongArch] Remove DAG combination for extractelement
Combination for `trunc+extend+extractelement` to a single
`extractelement` may occur error, because the high bits of the
extract index truncated by `trunc` operation are reserved
after the combination.

[lit] Fix filter-failed-rerun.py on readonly FSes (#177075)
This test invokes lit in a directory and then tries to overwrite
fail.txt within that directory. With the project sources mounted as
read-only, fail.txt ends up being marked readonly, which causes cp to
fail without -f. Use cp -f to ensure we overwrite the existing fail.txt.

This PR extends the multiclass to support two additional parameters: one for specifying whether an `AssemblerPredicate` should be generated, and another for dependent `SubtargetFeatures`. This allows 15 more definitions to be converted to use the multiclass.
[HWASAN] [RISC-V] Update EnableTaggingAbi for RISC-V linux. (#176616)
Enabling pointer tagging in the userspace ABI for RISC-V kernels differs
to that of Aarch64. It requires requesting a particular number of masked
pointer bits, an error is returned if the platform could not accommodate
the request:

when attempting to run instrumented programs in the spike simulator
running kernel release 6.18. This patch successfully allows the tagged

of just using `DITypeArray`.
