kgss: de-virtualize kgss_gssd_handle
The RPC client is more of a class rather than an instance. RPCs from
different VNETs are served by the same client. This makes the kgss layer
fully transparent to VIMAGE and not even required to be aware of it.
It is responsibility of the rpcsec_gss module to have curvnet set on the
calling thread when doing RPC calls via kgssapi.
This change should enable proper operation of an NFS server with gssd(8)
in a VIMAGE jail.

kgss: remove unnecessary CURVNET_SET() and kgss_gssd_handle checks
These RPC methods correctly acquire the kgss_gssd_handle later with call
to kgss_gssd_client().

kgss: remove KGSS_VNET_* macros family
The original idea was that something else than VNET(9) might be used for
kgss in jails, but that is very unlikely to happen.
Mechanical change done with sed+grep. No functional change.

[Clang][CodeGen] Report when an alias points to an incompatible target (#192397)
Add checks to ensure that an alias and its target have compatible types:
- Generate an error if a function alias points to a variable or vice
versa.
- Issue a warning for mismatches in function types.
- Ignore type discrepancies for variables.
This behavior aligns with similar diagnostics in GCC.

[DataLayout] Add null pointer value infrastructure
Add support for specifying the null pointer bit representation per address space
in DataLayout via new pointer spec flags:
- 'z': null pointer is all-zeros
- 'o': null pointer is all-ones
When neither flag is present, the address space inherits the default set by the
new 'N<null-value>' top-level specifier ('Nz' or 'No'). If that is also absent,
the null pointer value is unknown and LLVM will not fold based on it.
No target DataLayout strings are updated in this change. This is pure
infrastructure for a future ConstantPointerNull semantic change to support
targets with non-zero null pointers (e.g. AMDGPU).
Properly account for the display frame buffer in machine_bootmap[].
New pmap now at least get close to single-user on my slab. Issue
with Ethernet driver?
[LoongArch] Type legalize v2f32 loads by using an f64 load and a scalar_to_vector.
On 64-bit targets the generic legalize will use an i64 load and a
scalar_to_vector for us. But on 32-bit targets i64 isn't legal and the
generic legalizer will end up emitting two 32-bit loads.
