Subject: [patch] Make dse.c dumps less verbose unless dumping details

Hello,

Debugging a DSE bug, I found the dumps to be almost unusable because
they are so verbose. For my test case, the -fdump-rtl-dse1 dump is a
~17GB file without the attached patch (the test case has ~50000
insns). With the patch, all this extra information is only dumped with
-fdump-rtl-dse1-details.

Bootstrapped&tested on x86_64-unknown-linux-gnu and
powerpc64-unknown-linux-gnu. Will commit as obvious.

Ciao!
Steven
