kpdev42 requested review of this revision.

To make it possible to dump multiple objects during a single run, the
output files are named `/path/to/snippet-OPCODE-REPETITOR.o` with constant
parts omitted (for example, if dumping a single object file, its name is
exactly the value of `--dump-object-to-disk` option).

In dbc76ef791 <https://reviews.llvm.org/rGdbc76ef7915f925970f7bae1c5b79f3dcf55d85e>, the call to `writeObjectFile()` function was moved to
`runConfiguration()` because the latter is inherently serial to make the
"Check generated assembly with: ..." lines readable. Because now file
names are predictable, this message is not needed anymore, so the
`writeObjectFile()` function can be called at any suitable place.
