CodeGen: Fix handling of C++11 lambdas in profiling Until now we were generating duplicate counters for lambdas: one set in the function where the lambda was declared and another for the lambda itself. Instead, we should skip over the bodies of lambdas in their containing contexts. llvm-svn: 206081

InstrProf: Calculate a better function hash The function hash should change when control flow changes. This patch hashes the type of each AST node that affects counters, rather than just counting how many there are. These types are combined into a small enumerator that currently has 16 values. The new hash algorithm packs the enums for consecutively visited types into a `uint64_t`. In order to save space for new types, the types are assumed to be 6-bit values (instead of 4-bit). In order to minimize overhead for functions with little control flow, the `uint64_t` is used directly as a hash if it never fills up; if it does, it's passed through an MD5 context. <rdar://problem/16435801> llvm-svn: 206397
