diagnostic-show-locus.c: handle fixits on lines outside the regular ranges
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.

runtime: use -fgo-c-header to build C header file
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.

rs6000: Don't emit a use of LR in returns and sibcalls
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.

rich_location: add convenience overloads for adding fix-it hints
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.

compiler: add -fgo-c-header=FILE to create a C header
The new -fgo-c-header=FILE option will write a C header file defining
all the struct types and numeric const values in package scope. This
will be used when building the Go runtime package (libgo/go/runtime) to
generate a C header file that may be included by the C code in the C
runtime package (libgo/runtime).
This will ensure that the Go code and C code are working with the same
data structures as we convert the runtime from C to Go to upgrade to the
current GC runtime, notably the concurrent garbage collector.
