[Libclc-dev] libclc fails to compile with clang/llvm git

[Jan Vesely via Libclc-dev]

I'd say it was introduced by
https://github.com/llvm-mirror/clang/commit/14ebecf1b1fe06e58d0e61b10a0
cabeb72878efe
https://reviews.llvm.org/D24626

I'm not sure what the correct fix is. We'd probably need to implement
_half version in llvm IR.
