We support compressing debuginfo during codegen, but until this patch we didn't pass the flag to the linker. Doing so means we'll respect the requested compression even when building binaries or dylibs. This produces much smaller binaries: in my testing a debug build of ripgrep goes from 85M to 32M, and the target/ directory (after a clean build in both cases) goes from 508M to 329M just by enabling zlib compression of debuginfo.

Changes binary size, so don't rollup?

Good catch

@bors rollup=never

Note that debuginfo compression is off by default, so in the default configuration this does nothing.

self.sess.opts.unstable_opts.debuginfo_compression unstable, and looks like not used by bootstrap :-(

I think it should be safe to default debuginfo to compressed on all Linux platforms, but I've not done the research. I was figuring I'd kick the tires on compressed debuginfo at work for a while and then see about proposing changing the default.
