Eliminate fixit_hint class hierarchy

The original implementation of fix-it hints (r230674) had an abstract
base class "fixit_hint" and three subclasses, representing
each of insertions, replacements, and deletions.

Having multiple classes for fix-it hints was a nuisance, as it required
per-class logic everywhere that the hints were handled.

In r239632 I eliminated the deletion subclass in favor of replacement
with the empty string (two subclasses are easier than three).

This patch eliminates the class hierarchy altogether by implementing
insertion in terms of replacement, by representing replacements via
a half-open interval (so that for an insertion, start == next location,
and we're effectively replacing an empty range at the insertion point
with the new string).

This greatly simplifies the code for handling fix-it hints; for example
it allows removal of a parallel class hierarchy of line_event within
edit-context.c.

It also improves consolidation of hints: we can now consolidate
insertions at the same location, affecting a couple of tests
(selftest::test_one_liner_many_fixits and
gcc.dg/Wmissing-braces-fixits.c).

gcc/ChangeLog:
* diagnostic-show-locus.c (layout::get_expanded_location): Rewrite
to use new fixit_hint representation, using the "replace" logic.

* sem_util.ads, sem_util.adb (Might_Raise): New function
that replaces Is_Exception_Safe, but has the opposite
sense. Is_Exception_Safe was missing various cases -- calls inside
a pragma Debug, calls inside an 'if' or assignment statement,
etc. Might_Raise now walks the entire subtree looking for things
that can raise.
* exp_ch9.adb (Is_Exception_Safe): Remove.

Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
constants where possible).
* exp_ch7.adb: Rename Is_Protected_Body -->
Is_Protected_Subp_Body. A protected_body is something different
in the grammar.

Valid_Conversion, to determine whether a type conversion appears
as (or within) an actual for a formal object.  Type conversions
in instances are not rechecked in Valid_Conversion because
visibility changes between generic location andi instance may
lead to spurious errors, but conversions within an actual must be
fully checked, and they are not fully resolved when pre-analyzing

[AArch64] Fix for gcc-7 regression PR 80530

This patch fixes the regression caused by the changes to add square root
estimation when compiling for xgene-1 or exynos-m1 targets.

The issue is that the expand path for the reciprocal estimate square
root pattern assumes that pattern cannot fail once it has been decided
that this expansion path is available, but because the logic deep inside
aarch64_emit_approx_sqrt() differs from use_rsqrt_p() the two disagree
as to what is safe.

This patch refactors the logic to ensure that we cannot unknowingly make
different choices here.

PR target/80530
* config/aarch64/aarch64.c (aarch64_emit_approx_sqrt): Ensure
that the logic for permitting reciprocal estimates matches that
