CodeGen: Include a function hash in instrumentation based profiling The hash itself is still the number of counters, which isn't all that useful, but this separates the API changes from the actual implementation of the hash and will make it easier to transition to the ProfileData library once it's implemented. llvm-svn: 204186

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

Revert "CodeGen: Use a binary format for instrumentation based profiling" I've clearly done something wrong with how to get this to link correctly. Reverting for now. This reverts commit r203711. llvm-svn: 203712
