[C++][Modules] Don't insert `#include` before GMF when `-include` used (#212533)
Clang currently emits command-line implicit inputs such as `-imacros`,
`-include-pch`/`-include-pth`, and `-include` as part of the predefines
buffer. This causes them to be processed before the main source file.
For a C++20 module unit with a global module fragment:
```cpp
module;
export module M;
```
a force-included header containing declarations was effectively
processed as:
```cpp
#include "Header.h"
module;

[MCParser,test] Improve macro argument charset test (#218828)
'@', '#', and '?' are assembly identifier characters, but they terminate

nfs: New sysctl node vfs.nfsd.maxexportspermount.
Limits the number of different ways a single mount point can be
exported. Default is limited to 256; can be expanded by sysctl up to
anything that won't overflow kva.
XXX Should prevent increasing it at securelevel>0.

[AMDGPU] Correct DS FIFO buffer size semantics
There was some ambiguity in how buffersize 0 and 1 are handled. The
correct semantics are:
- `BufferSize == 0`: unlimited, no FIFO stall
- `BufferSize == 1`: unbuffered, only one instruction in flight
- `BufferSize > 1`: buffered FIFO
Handle DS FIFO accounting edge cases
Saturate hardware-unit pressure decrements and treat buffer sizes zero
and one as disabling buffering to avoid underflow and inconsistent stall
costs.
[AMDGPU] Use DS latency for FIFO scheduling
Use instruction latency for DS hardware-unit cycle accounting so the FIFO
model can identify a full buffer. Add focused MIR coverage for the resulting
stall cost and scheduling decision, and regenerate the integration checks.

[SSAF][SourceTransform] Add '--ssaf-link-unit-id=' for specifying link unit identifiers
The source-transformation pass takes WPA results as input, where
entities are named under link-unit and compilation-unit namespaces.
To associate ASTNodes with entities, the source-transformation pass
needs to know both link-unit and compilation-unit IDs. Such information
is provided by the caller.

[RISCV][GlobalISel] Legalize and select G_PREFETCH (#215466)
GlobalISel aborted on `llvm.prefetch` ("unable to legalize
`G_PREFETCH`") while SDAG lowers it to `prefetch.r/w/i`. Add a legalizer
rule marking `G_PREFETCH` legal for p0 addresses, and a custom selector
since the SDAG patterns use the `AddrRegImmLsb00000` complex pattern
that the GISel pattern importer does not auto-translate. The selector
picks `prefetch.r/w/i` from the rw/cache-type immediates and folds a
`simm12_lsb00000` offset when present, matching SDAG.
[RISCV][GlobalISel] Legalize readcyclecounter/readsteadycounter (#217535)
Add a legalizer rule for G_READCYCLECOUNTER/G_READSTEADYCOUNTER. On RV64
they are legal and select via the existing tablegen Pats
(rdcycle/rdtime). On RV32 lower them to the ReadCounterWide target
pseudo, which FinalizeISel expands into the re-read-the-high-half loop
(emitReadCounterWidePseudo) — the same expansion SelectionDAG uses.
