[clang] Improve diagnostics for `__builtin_align` builtins with floating/member pointer operands (#192650)
Improve diagnostics for `__builtin_align_up`, `__builtin_align_down`,
and `__builtin_is_aligned` when the first operand has an invalid type.
Clang already emits `err_typecheck_expect_scalar_operand` for
unsupported operands, but the message is generic. This patch adds
follow-up notes to clarify three common invalid cases:
* floating point operands (“floating point types are not allowed here”)
* C++ member pointer operands (“member pointers are not allowed here”)
* plain-function-pointer ("function pointers are not allowed here")
[LoongArch] Select `V{AND,OR,XOR,NOR}I.B` for bitwise with byte splat immediates (#192217)
The `V{AND,OR,XOR,NOR}I.B` instructions operate on byte elements and
accept an 8-bit immediate. However, when the same byte splat constant is
used with wider vector element types (e.g. v8i16, v4i32, v2i64),
instruction selection currently falls back to materializing the constant
in a temporary register.
```
vrepli.b -1
vxor.v
```
even though the immediate form is available:
```
vxori.b 255
```

kshim/usb: Add build option.
Add WITH{,OUT}_LOADER_USB to build the kshim usb library. Nothing
in-tree uses it, but this will make it easier to keep building. Updated
src.conf.5 with a few extra changes...
