Subject: [PATCH] compiler_types: Remove unnecessary indirection in
 compiletime_assert()

compiletime_assert() is the only user of _compiletime_assert(), which
uses __compiletime_assert() directly with no modification to arguments.
Remove _compiletime_assert() and use __compiletime_assert() directly.
