libgo: avoid confusion in upcase_fields in mksysinfo.sh
The mksysinfo.sh script could get confused when there were multiple
types starting with the same name. I believe this is the underlying
cause of GCC PR 78172.
Also redirect a grep to /dev/null to avoid extraneous messages during
the build.

Since sparc is a valid architecture, the name of
getrandom_linux_sparc.go means that it will be ignored on sparc64,
even though it's whitelisted with a +build line.
On SPARC, clone has a unique return value convention which requires
some inline assembly to convert it to the normal convention.

This is a step toward a version of mksysinfo that generates information
for the runtime package. This will be used to generate the
runtime_sysinfo.go file, which is currently directly generated by a
Makefile target.

Use the new -fgo-c-header option to build a header file for the Go
runtime code in libgo/go/runtime, and use the new header file in the C
runtime code in libgo/runtime. This will ensure that the Go code and C
code share the same data structures as we convert the runtime from C to
Go.
The new file libgo/go/runtime/runtime2.go is copied from the Go 1.7
release, and then edited to remove unnecessary data structures and
modify others for use with libgo.
The new file libgo/go/runtime/mcache.go is an initial version of the
same files in the Go 1.7 release, and will be replaced by the Go 1.7
file when we convert to the new memory allocator.
The new file libgo/go/runtime/type.go describes the gccgo version of the
reflection data structures, and replaces the Go 1.7 runtime file which
describes the gc version of those structures.
Using the new header file means changing a number of struct fields to
use Go naming conventions (that is, no underscores) and to rename
constants to have a leading underscore so that they are not exported
from the Go package. These names were updated in the C code.
The C code was also changed to drop the thread-local variable m, as was
done some time ago in the gc sources. Now the m field is always
accessed using g->m, where g is the single remaining thread-local
variable. This in turn required some adjustments to set g->m correctly
in all cases.
Also pass the new -fgo-compiling-runtime option when compiling the
runtime package, although that option doesn't do anything yet.

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.

From Rainer Orth.
The recent godump changes broke Solaris 11.1+ bootstrap in
libgo: before, gen-sysinfo.so had
type _zone_net_addr_t struct { zna_family uint16; zna_plen uint16; zna_addru struct { znau_addr6 _in6_addr; }; }
which was filtered out by mksysinfo.sh due to the use of
_in6_addr.
After the change, there's now
type _zone_net_addr_t struct { zna_family uint16; zna_plen uint16; zna_addru struct { znau_addr6 [16]byte; Godump_0_align [0]uint32; }; }
instead, not filtered, but added a second time by the
_zone_net_addr_t code in mksysinfo.sh, which leads to
redefinition warnings/errors.
Simply removing the old _zone_net_addr_t fragment fixes this
and restores bootstrap.
