[llvm] [llc] Add -M for InstPrinter options (PR #121078)

[Sergei Barannikov via llvm-commits]

The way it is currently implemented it only works when invoking llc directly.
It would be great if the option could be set by the compiler driver, which passes options in memory.
See https://github.com/llvm/llvm-project/blob/eb549da9e5c1e626edb14ba9ce43e46ad3d088af/clang/tools/driver/cc1as_main.cpp#L538 for a few examples.

Some targets prefer to *not* print aliases by default; there should be a way of enabling this behavior.
