fix-it hints: insert_before vs insert_after

The API for adding "insert text" fix-it hints was unclear
about exactly where the text should be inserted relative
to the given insertion point.

This patch clarifies things by renaming the pertinent methods from
  richloc.add_fixit_insert
to
  richloc.add_fixit_insert_before
and adding:
  richloc.add_fixit_insert_after

The latter allows us to consolidate some failure-handling into
class rich_location, rather than having to have every such diagnostic
check for it.

The patch also adds a description of how fix-it hints work to the
comment for class rich_location within libcpp/include/line-map.h.

gcc/c-family/ChangeLog:
* c-common.c (warn_logical_not_parentheses): Replace

Fix suggestions for non-trivial Wformat type cases (PR c/72858)

gcc/c-family/ChangeLog:
PR c/72858
* c-format.c (argument_parser::check_argument_type): Add params
"type_start" and "conversion_char".  Use the former to generate
offset_to_type_start and pass it and conversion_char to
check_format_types.
(check_format_info_main): Capture the start of the type
information as "type_start", and pass it an format_char
to arg_parser.check_argument_type.
(check_format_types): Provide an example in the leading comment.
Add params "offset_to_type_start" and "conversion_char"; pass
them to format_type_warning calls.
(test_get_modifier_for_format_len): Likewise.
(matching_type_p): New function.
(get_format_for_type): Add param "conversion_char" and move

Add params "offset_to_type_start" and "conversion_char".  Replace
call to get_format_for_type with call to get_corrected_substring
and move rejection of hints for widths/precisions there.
(assert_format_for_type_streq): Add param "conversion_char".
(ASSERT_FORMAT_FOR_TYPE_STREQ): Add param CONVERSION_CHAR.
(test_get_format_for_type_printf): Add conversion chars to the

runtime/internal/sys: new package, API copied from Go 1.7

    Copy over the Go 1.7 runtime/internal/sys package, but instead of having
    separate files for each GOARCH and GOOS value, set the values in
    configure.ac and write them out in Makefile.am.  Setting the values in
    configure.ac should make it easier to add new processors.

    Remove the automake GOARCH conditionals, which are no longer used.
    Leave the GOOS conditionals for now, as they are used for the C runtime
    package.

Define TS 18661-1 type width macros in <limits.h> and <stdint.h>.

TS 18661-1 defines <limits.h> and <stdint.h> macros for widths of
standard integer types and the typedefs defined in, or whose limits
are defined in, <stdint.h>.  (The connection to the main
floating-point subject matter of TS 18661-1 is that these are intended
to be used with the fromfp functions to convert from floating point to
integer types of any width in any rounding direction, though these
macros may be of more general use.)

This patch implements support for these macros in GCC's <limits.h> and
<stdint.h>.  To avoid needing to implement fixincludes for system
headers where GCC wraps the system libc's <stdint.h> in hosted mode,
the test for the <stdint.h> macros uses -ffreestanding (I'll add the
macros to glibc's headers separately) - but as usual for new features
in these headers, platforms (primarily OpenBSD) that use USER_H to
avoid using GCC's headers at all will have failures until the system
headers have the feature added or appropriate fixincludes are
implemented.

The header macros are implemented using appropriate new predefined
macros, with the code avoiding defining more such macros than
necessary (so one predefined macro suffices for corresponding signed
and unsigned types, while no such predefined macros are needed for the
exact-width types such as int8_t).

libgcc complex multiply is meant to eliminate excess
precision from certain internal values by forcing them to memory in
exactly those cases where the type has excess precision.  But in
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01894.html I
accidentally inverted the logic so that values get forced to memory in
exactly the cases where it's not needed.  (This is a pessimization in
the no-excess-precision case, in principle could lead to bad results
depending on code generation in the excess-precision case.  Note: I do
not have a test demonstrating bad results.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu.  Code size
went down on x86_64 as expected; old sizes:

   text    data     bss     dec     hex filename
    887       0       0     887     377 _muldc3.o
    810       0       0     810     32a _mulsc3.o
   2032       0       0    2032     7f0 _multc3.o
    983       0       0     983     3d7 _mulxc3.o

New sizes:

    847       0       0     847     34f _muldc3.o
    770       0       0     770     302 _mulsc3.o

Improve aarch64_legitimize_address - avoid splitting the offset if it is supported.

Improve aarch64_legitimize_address - avoid splitting the offset if it is
supported.  When we do split, take the mode size into account.  BLKmode
falls into the unaligned case but should be treated like LDP/STP.
This improves codesize slightly due to fewer base address calculations:

int f(int *p) { return p[5000] + p[7000]; }

Now generates:

f:
add x0, x0, 16384
ldr w1, [x0, 3616]
ldr w0, [x0, 11616]
add w0, w1, w0
ret

instead of:

f:
add x1, x0, 16384
add x0, x0, 24576
ldr w1, [x1, 3616]
ldr w0, [x0, 3424]
add w0, w1, w0
ret

* config/aarch64/aarch64.c (aarch64_legitimize_address):
Avoid use of base_offset if offset already in range.
