[patch] Remove target.h and alloc-pool.h from lto-streamer.h.

[Andrew MacLeod <amacleod at redhat dot com>]

target.h and alloc-pool.h are not required by any of the streamer header 
files to compile, so I flattened those 2 includes from lto-streamer.h.
plugin-api.h, gcov-io.h and diagnostic.h are all required to parse 
lto-streamer.h, so I left those in the file.

I then ran the include reducer on all of the files which were affected 
by by the flattening (there were 38). I had it only consider the 
affected files : target.h, alloc-pool.h and lto-streamer.h.
Only 22 of the 38 files now show any change, and in many of those cases 
it was removing lto-streamer.h itself that was the end result :-)  So 
its a much cleaner patch now :-)

Bootstraps on x86_64-unknown-linux-gnu with no new regressions.
OK for trunk?
