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.

compiler: add abstraction layer for sha1 checksums.
Add new interface for the front end code to use when computing SHA1

No change in functionality for gccgo; this is an enabling change to

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).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
