Subject: [PATCH] Bug 2067405 - mark hal's sInitialized as maybe_unused.
 r=gsvelto

Every read of sInitialized happens inside a MOZ_ASSERT, so opt builds only ever write to it. clang 23
flags that under -Wunused-but-set-global, which -Wall now enables transitively via
-Wunused-but-set-variable, busting the plain clang-trunk build.
