0c139883f4 [libc] Fix server code when GPU is acting as the server 
Summary:
Small fix that just ignores all the extra lanes if we're running the
server from a platform that potentially has more.

8f410b491e [libc] Fix incorrect macro usage in shared/sign.h (#150140) 
This patch corrects the `using`-declaration in `libc/shared/sign.h`.

The previous change (#150083) incorrectly used the `LIBC_NAMESPACE_DECL`
macro. This is corrected to use `LIBC_NAMESPACE`.

d8e55c842b [libc] Expose the Sign type for shared use (#150083) 
This patch exposes the internal `Sign` type for shared use by other LLVM
subprojects, following the pattern established by `FPBits`.

The `FPBits` utility is exposed via `libc/shared/fp_bits.h`. However,
its public interface relies on the `Sign` type for, e.g., creating
signed infinities and returning the sign of a value. Currently, users of
the shared `FPBits` have no way to access the `Sign` type.

Following the existing pattern for sharing `libc` utilities, this patch
adds a new public header `libc/shared/sign.h`. This header simply
includes the internal `src/__support/sign.h` and brings the `Sign` type
into the `shared` namespace.

8437b7f558 [libc] Make RPC server handling header only (#131205) 
Summary:
This patch moves the RPC server handling to be a header only utility
stored in the `shared/` directory. This is intended to be shared within
LLVM for the loaders and `offload/` handling.

Generally, this makes it easier to share code without weird
cross-project binaries being plucked out of the build system. It also
allows us to soon move the loader interface out of the `libc` project so
that we don't need to bootstrap those and can build them in LLVM.
