[AMDGPU][NFC] Use generated hasMinMaxI64Insts subtarget feature query
Replace the custom GCNSubtarget::hasIntMinMax64 helper with
the generated hasMinMaxI64Insts from AMDGPUSubtargetFeature.
[LoopInterchange] Prevent interchange when memory-accessing calls exist (#200828)
Previously loop-interchange can be applied even though the loop has call
instructions which may access the memory. The root cause of this problem
is that the implementation didn't match the comment, like below:
```cpp
// readnone functions do not prevent interchanging.
if (CI->onlyWritesMemory() || isa<PseudoProbeInst>(CI))
continue;
```
However, I think ensuring `readnone` is insufficient in the first place,
because the LLVM Language Reference states about `readnone` as follows:
```
This attribute indicates that the function does not dereference that pointer argument, even though it may read or write the memory that the pointer points to if accessed through other pointers.
```

linux: Implement PTRACE_GETREGSET NT_PRFPREG and NT_X86_XSTATE
Implement NT_PRFPREG and NT_X86_XSTATE for PTRACE_GETREGSET on amd64.
Chrome's crashpad handler uses these to collect floating-point and
extended CPU register state for crash dumps.
Other architectures retain the previous EINVAL stub behavior.

linux: Add linux_pt_fpregset and bsd_to_linux_fpregset() for amd64
Add struct linux_pt_fpregset, the amd64 Linux NT_PRFPREG payload,
corresponding to user_i387_struct in Linux. The struct describes
the 512-byte FXSAVE area as exposed by PTRACE_GETREGSET.
Add bsd_to_linux_fpregset() to translate from FreeBSD's struct fpreg
to struct linux_pt_fpregset. Fields are extracted from the fpr_env[]
array which stores the FXSAVE environment packed as four 64-bit words.
The FP and XMM register banks are bulk-copied as opaque byte arrays.

[clang][CodeGen] Drop TBAA metadata emission on FP libcalls (#200752)
TBAA annotation on FP libcalls has been superseded by
recently-introduced `llvm.errno.tbaa` module-level metadata.
Prevent daily(8) from deleting /tmp/run/user/* direct subdirectories
These are directories that are created by
setusercontext(LOGIN_SETXDGENV) and should be available as long as
a session with the XDG_RUNTIME_DIR env variable pointing at them exists.
Since we don't track such sessions, we can't have daily(8) remove such
directories blindly. This looks like an oversight in the initial commit.

[LifetimeSafety] Prevent false-negative lifetimebound verification when origin escapes in an unrelated manner (#200786)
This PR removes a false-negative `[[lifetimebound]]` verification result
that occurs when the annotated attribute escapes via unrelated origin
escape kinds (escape through global, escape through field).
Change summary:
- `Checker.cpp` has function `checkAnnotations` which checks if an
escaping `Origin` was an annotated parameter. Modified the logic there
to only verify `[[lifetimebound]]` in the case that the escape was
through a return statement.
Fixes #200412
