Hi,
while debugging verify_type ICE I noticed that we output debug info to slim-lto
files.
This debug info is never used for anything and should be omitted. I wonder if
this
can go also to rleease branches since it will likely make the slim files
smaller.
Of course things will change with early debug, but even there we do not want to
output
all debug this way.
Bootstrapped/rgtested x86_64-linux, comitted.
