Original change's description:
> Suppress memory leaks detected by LSAN
>
> In order to be able to land SwANGLE in Chromium, this cl adds
> suppressions for memory leaks detected by LSAN. Some of these
> should be fixed and some are intentional leaks of global
> variables.
>
> This cl should allow the linux_chromium_asan_rel_ng bot to pass
> while using SwANGLE.
