Add a lto-section-names.h header


This is a change from the gomp4 branch which I think could go on trunk now. It removes some duplicated definitions and puts them in a header file. More definitions will be added to that header once offloading is implemented as on the branch.

Bootstrapped and tested on x86_64-linux, ok?
