ObjectLinker::doLto() had convoluted flow, duplicated pieces of code in different branches, etc. Simplify and clarify it. There is no functional change, except when both `lto-asm-file` and `lto-output-file` specified, on Hexagon only, a misleading message about using the asm file is not printed. When `lto-output-file`, the assembly inputs are ignored, this did not change, and the message was incorrect. Signed-off-by: Alexey Karyakin <akaryaki@qti.qualcomm.com>

--lto-obj-path will work differently than in lld. In lld, it creates copies of LTO output files, which means with `-save-temps` each object file will be written twice. Instead, we will redirect output files to the location specified by `--lto-obj-path`, which means these files will not be written to the `-save-temps` location if it is specified.
