[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154444 91177308-0d34-0410-b5e6-96231b3b80d8
