When trying to analyze why Graphite does not handle a loop nest, it is easy to
look in the dumps of -fdump-tree-graphite-all to guess what has to be changed to
catch the loop. This patch makes the dumps a bit more verbose and useful.
* graphite-scop-detection.c: Include gimple-pretty-print.h.
(stmt_simple_for_scop_p): Print when a stmt is not handled in Graphite.
(scopdet_basic_block_info): Print when a loop or bb cannot be
represented in Graphite.

During the gccgo build define constants from
some header files are processed by mksysinfo.sh and
added to syscall.go. In some cases the constants
are based on macros which are not processed
correctly by mksysinfo.sh. This adds the support
to generate the correct values for the TUN* constants
from linux/if_tun.h.
