This patch adds legitimize_address_displacement hook so that stack accesses
with large offsets are split into a more efficient sequence. Unaligned and
TI/TFmode use a 256-byte range, byte and halfword accesses use a 4KB range,
wider accesses use a 16KB range to maximise the available addressing range
and increase opportunities to share the base address.

‘struct’ keyword to refer to the type

However when using the (not yet in trunk) option
-fdiagnostics-generate-patch,
the generated patch is nonsensical:
-foo_t *foo_ptr;

The diagnostic_show_locus implementation determines the set
of line spans that need printing based on the ranges within the
rich_location (in layout::calculate_line_spans).
Currently this doesn't take into account fix-it hints, and hence
we fail to print fix-it hints that are on lines outside of
those ranges.
This patch updates the implementation to take fix-it hints into
account when calculating the pertinent line spans, so that such fix-it
hints do get printed. It also adds some validation, to ensure that
we don't attempt to print fix-its hints affecting a different source
file.

This patch eliminates the hard-coded limits within rich_location
(up to 3 ranges, up to 2 fixits). The common case is still
handled by embedding the values inside rich_location - it only

be fast. This is implemented via a new container class,
semi_embedded_vec <T, N>.

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.
