[ELF] Dump symbols ordered by profiled guided section layout to file. Patch by Tiancong Wang. In D36351, Call-Chain Clustering (C3) heuristic is implemented with option --call-graph-ordering-file <file>. This patch adds a flag --print-symbol-order=<file> to LLD, and when specified, it prints out the symbols ordered by the heuristics to the file. The symbols printout is helpful to those who want to understand the heuristics and want to reproduce the ordering with --symbol-ordering-file in later pass.
