Kostya Serebryany 3386d25257 [asan] Optimize accesses to global arrays with constant index ... Summary: Given a global array G[N], which is declared in this CU and has static initializer avoid instrumenting accesses like G[i], where 'i' is a constant and 0<=i<N. Also add a bit of stats. This eliminates ~1% of instrumentations on SPEC2006 and also partially helps when asan is being run together with coverage.
