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;

Fix the fix-its by adding a trailing space to each one, giving:

  -foo_t *foo_ptr;
  +struct foo_t *foo_ptr;

From-SVN: r239908

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
uses dynamic allocation if these limits are exceeded, so
creation of rich_location instances on the stack should still
be fast.  This is implemented via a new container class,
semi_embedded_vec <T, N>.

gcc/ChangeLog:
	* diagnostic-show-locus.c (colorizer::begin_state): Support more
	than 3 ranges per diagnostic by alternating between color 1 and
	color 2.
	(layout::layout): Replace use of rich_location::MAX_RANGES
	with richloc->get_num_locations ().
	(layout::calculate_line_spans): Replace use of
	rich_location::MAX_RANGES with m_layout_ranges.length ().
	(layout::print_annotation_line): Handle arbitrary numbers of
	ranges in caret-printing by defaulting to '^'.
	(selftest::test_one_liner_many_fixits): New function.
	(test_diagnostic_show_locus_one_liner): Call it.
	* diagnostic.c (diagnostic_initialize): Update for renaming
	of rich_location::MAX_RANGES to
	rich_location::STATICALLY_ALLOCATED_RANGES.
	* diagnostic.h (struct diagnostic_context): Likewise.

gcc/testsuite/ChangeLog:
	* gcc.dg/plugin/diagnostic-test-show-locus-bw.c
	(test_many_nested_locations): New function.
	* gcc.dg/plugin/diagnostic_plugin_test_show_locus.c
	(test_show_locus): Handle "test_many_nested_locations".

	(rich_location::MAX_RANGES): Rename to...
	(rich_location::STATICALLY_ALLOCATED_RANGES): ...this.
	(rich_location::MAX_FIXIT_HINTS): Rename to...
	(rich_location::STATICALLY_ALLOCATED_RANGES): ...this, and make

Split out a new base class for temp_source_file, named_temp_file,
moving the deletion to the base class dtor, so that we can write
out temporary files in other ways in selftests.

	ctor.
	(selftest::temp_source_file::~temp_source_file): Move to...
	(selftest::named_temp_file::~named_temp_file): ...here.
	(selftest::test_named_temp_file): New function.
	(selftest::selftest_c_tests): Call test_named_temp_file.
	* selftest.h (class named_temp_file): New class.
	(class temp_source_file): Convert to a subclass of named_temp_file.
