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.

In r237714 I added fix-it hints to the C frontend for missing "struct"
keywords e.g.:
spellcheck-typenames.c:69:1: error: unknown type name ‘foo_t’; use
‘struct’ keyword to refer to the type
foo_t *foo_ptr;
^~~~~
struct
However when using the (not yet in trunk) option
-fdiagnostics-generate-patch,
the generated patch is nonsensical:
-foo_t *foo_ptr;
+structfoo_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,

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.

The exit block (to which every return artificially jumps) already has
a use of LR. The LR use in all returns and sibcalls is an anachronism,
probably made unnecessary by the dataflow merge. The simple_returns
that shrink-wrapping generates also do not have such a use. Newer
backends do not do this either it seems.
With this use removed, a normal return is no longer a parallel but just
a return insn, and cfgcleanup then can transform conditional jumps to
those into conditional returns.
This splits the return emission code with restoring_FPRs_inline from
that without it; this is simpler code, fewer lines, and less indentation.

Adding a fix-it hint to a diagnostic usually follows one of these
patterns:
(a) an insertion fix-its, with the insertion at the primary caret location
(b) a removals/replacements, affecting the range of the primary location
(other cases are possible, e.g. multiple fix-its, and affecting other
locations, but these are the common ones)
Given these common cases, this patch adds overloads of the rich_location
methods for adding fix-it hints, so that the location information can
be omitted if it matches that of the primary location within the
rich_location.
Similarly when adding "remove" and "replace" fix-it hints to a diagnostic,
it's tedious to have to extract the source_range from a location_t
(aka source_location). To make this more convenient, this patch
adds overload of the rich_location::add_fixit_remove/replace methods,
accepting a source_location directly.
The patch updates the various in-tree users of fix-it hints to use
the new simpler API where appropriate. I didn't touch the case where
there are multiple fix-its in one rich_location, as it seems better to
be more explicit about locations for this case (adding a pair of parens
in warn_logical_not_parentheses).
The above makes the gcc_rich_location::add_fixit_misspelled_id overload
taking a const char * rather redundant, so I eliminated it.

Nothing uses MQ anymore, but it still shows up in all the dump files.
This patch removes it from CALL_REALLY_USED_REGISTERS so that that does
not happen anymore (it is still a fixed register, there should be no
functional change).
* config/rs6000/rs6000.h (CALL_REALLY_USED_REGISTERS): Do not
include MQ.

Currently the fix-it validator rejects ad-hoc locations.
Fix this by calling get_pure_location on the input locations to
add_fixit_insert/replace. Doing so requires moving get_pure_location
from gcc to libcpp.
gcc/ChangeLog:
* diagnostic-show-locus.c
(selftest::test_one_liner_fixit_validation_adhoc_locations): New
function.
(selftest::test_diagnostic_show_locus_one_liner): Call it.
* input.c (get_pure_location): Move to libcpp/line-map.c.
* input.h (get_pure_location): Convert decl to an inline function
calling implementation in libcpp.
libcpp/ChangeLog:
* include/line-map.h (get_pure_location): New decl.
* line-map.c (get_pure_location): Move here, from gcc/input.c, adding
a line_maps * param.
(rich_location::add_fixit_insert): Call get_pure_location on "where".
(rich_location::add_fixit_replace): Call get_pure_location on the
end-points.
