Suppress core.FixedAddressDereference static analyzer warnings in bmalloc's
BCRASH() macro
<https://bugs.webkit.org/show_bug.cgi?id=318543>
<rdar://181315666>
Reviewed by Yusuke Suzuki.
The clang static analyzer's `core.FixedAddressDereference` checker
reports a dereference of a fixed address wherever an assertion-failure
path reaches `BCRASH()` because the macro's deliberate
`*(int*)0xbbadbeef = 0;` fail-fast store writes through a literal
address.
Mark the store as an intentional false positive with a leading
`[[clang::suppress]]` attribute inside `BCRASH()` itself.
No new tests since this change is not directly testable.
