[lto] Add beginning of -save-temps option. Summary: This is useful for debugging issues with LTO. The option follows the analogous option in ld64 and the gold plugin (per Rafael's suggestion). For starters, this only dumps the combined bitcode file. In a future patch I will add dumping for the .o file. The naming of the output follows ld64's convention which is slightly more consistent IMO (consistent `.lto.<extension>` for all the files).

Attempt to fix non-determinism in test. Otherwise it could just use a leftover a.out from some other test. llvm-svn: 271820

[LTO] Fix -save-temps in case -o is not specified. Currently we create a file called .lto.bc. In UNIX, ls(1) by default doesn't show up files starting with a dot, as they're (only by convention) hidden. This makes the output of -save-temps a little bit hard to find. Use "a.out.lto.bc" instead if the output file is not specified. While here, change an existing -save-temps test to exercise this more interesting behaviour. llvm-svn: 265254

[lto] Add saving the LTO .o file to -save-temps. Summary: This implements another part of -save-temps. After this, the only remaining part is dumping the optimized bitcode. But currently LLD's LTO doesn't have a non-intrusive place to put this. Eventually we probably will and it will make sense to add it then.
