In commit 9ced3148ca ("util: avoid calling UNREACHABLE(str) macro
without arguments", 2025-07-30) the argument type check in the
UNREACHABLE(str) macro in src/util/macros.h was improved to also avoid
calling it without arguments, but the definition in
src/compiler/libcl/libcl.h was not updated.
Apply a similar change to src/compiler/libcl/libcl.h to keep the C and
CL macros in sync.
