Kostya Serebryany 3047a70ed9 [tsan] two more compile-time optimizations: ...

- don't isntrument reads from constant globals.
Saves ~1.5% of instrumented instructions on CPU2006
(counting static instructions, not their execution).
- don't insrument reads from vtable (which is a global constant too).
Saves ~5%.

I did not measure the run-time impact of this,
but it is certainly non-negative.
