Summary: Add support to read profiles collected without LBR. This involves adapting our data aggregator perf2bolt and adding support in llvm-bolt itself to read this data. This patch also introduces different options to convert basic block execution count to edge count, so BOLT can operate with its regular algorithms to perform basic block layout. The most successful approach is the default one. (cherry picked from FBD5664735)
