[LoongArch] Combine rounded vector shifts to VSRLR/VSRAR (#192921)
Add DAG combines to recognize canonical rounded shift patterns and lower
them to target-specific vector rounded shift instructions.
The combines match vector arithmetic and logical right shifts with
rounding implemented as:
```
add (srl/sra X, shift),
(and (srl X, shift-1), 1)
```
and the shift-by-1 variant:
```
add (srl/sra X, 1),
(and X, 1)
```

[RISCV][GlobalISel] Support RISC-V specific inline asm constraints: 'I', 'J', 'K' and 'S' (#193765)
This patch implements some target-specific constraints for RISC-V: `I`,
`J`, `K` and `S`. These constraints are all for immediate values except
for `S`. The handling of these constraints is implemented with by adding
`RISCVInlineAsmLowering` subclass of `InlineAsmLowering`.
[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.

[MC] Change MCContext::getTargetOptions to return a reference. NFC (#194112)
Since #180464, MCAsmInfo stores a non-null MCTargetOptions pointer set
by
TargetRegistry::createMCAsmInfo, and MCContext's constructor asserts
that
MAI->getTargetOptions() is non-null. Return the options by reference
instead of by pointer so callers can drop the null handling.
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.
