[lld-link] implement -thinlto-index-only Summary: This implements -thinlto-index-only, -thinlto-index-only:, and -thinlto-emit-imports-files options in lld-link. They are analogous to their counterparts in ld.lld: -thinlto-index-only causes us to perform ThinLTO's thin link and write index files, but not perform code generation. -thinlto-index-only: does the same, but also writes a text file listing the native object files expected to be generated. -thinlto-emit-imports-files creates a text file next to each index file, listing the files to import from.

[ThinLTO] Compute the basic block count across modules. Summary: Count the per-module number of basic blocks when the module summary is computed and sum them up during Thin LTO indexing. This is used to estimate the working set size under the partial sample PGO. This is split off of D79831.

[COFF] Fix to not add archive name to buffer identifiers when they come from thin archives. Currently lld adds the archive name to MemoryBufferRef identifiers in order to ensure they are unique. For thin archives, since the file name is already unique and we want to keep the original path to the file, don't add the archive name.
