[libc-commits] [libc] [libc] Initial support for parsing SPIR-V for GPU libc (PR #128570)

[Joseph Huber via libc-commits]

https://github.com/jhuber6 created https://github.com/llvm/llvm-project/pull/128570

Summary:
Some day we'd like to support this, add some initial support for parsing
the triple so it will at least attempt to build.
