["Sourceware to Gerrit sync (Code Review)" <gerrit@gnutoolchain-gerrit.osci.io>]

The original change was created by Tom Tromey.

Fix opcodes includes

Now that gdb can unconditionally use a -I pointing at the top of the
source tree, we can remove the ugly "../opcodes/" formulation that was
needed earlier.  This patch adds the -I and cleans up these includes.
