[PATCH] D14798: [LSan] Fix tests with some libstdc++ implementations.

Newer libstdc++ has global pool, which is filled with objects
allocated during libstdc++ initialization, and never released.
Using use_globals=0 in the lit tests results in these objects
being treated as leaks.

Fix this by porting several tests to plain C, and introducing
a simple sanity test case for __lsan::ScopedDisabler.
