Trivial patch to add pass-instances.def to installed headers

We install the header "pass_manager.h", but it can't be included by a plugin,
since it includes "pass-instances.def", and we don't current install that.

/home/david/coding/gcc-python/gcc-svn-4.9/install/lib/gcc/x86_64-unknown-linux-gnu/4.9.2/plugin/include/pass_manager.h:123:30:
fatal error: pass-instances.def: No such file or directory
 #include "pass-instances.def"

Affects 4.9 branch (e.g. r215685), and, I believe, trunk.

Marking as [Regression] since this currently makes it impossible to access the
"roots" of the pass tree ("all_passes" et al) from a plugin in 4.9+, since they
were moved from being globals to being member data of the pass_manager in 4.9,
hence we need to include pass_manager.h for that.

(My fault, sorry: I was the one who moved these from being globals to being
member data.  The gcc-python-plugin needs this, and hence this is one thing
blocking that plugin from being built against 4.9)

Am currently verifying the obvious patch.
