Fraser Cormack d51525ba36 [libclc] Move lgamma, lgamma_r & tgamma to CLC library (#134053)
Also enable half-precision variants of tgamma, which were previously
missing.

Note that unlike recent work, these builtins are not vectorized as part
of this commit. Ultimately all three call into lgamma_r, which has heavy
control flow (including switch statements) that would be difficult to
vectorize. Additionally the lgamma_r algorithm is copyrighted to SunPro
so may need a rewrite in the future anyway.

There are no codegen changes (to non-SPIR-V targets) with this commit,
aside from the new half builtins.
