* gcc-interface/trans.c (assoc_to_constructor): Make sure
Corresponding_Discriminant is only called on discriminants.
Skip the saving of the result only for them.

Fix broken pr78138.c for avr

The declaration for memcpy had the size parameter declared as
unsigned long. For avr, __SIZE_TYPE__ is unsigned int, and
this caused a builtin-declaration-mismatch warning, resulting
in a couple of FAILs.

Fixed by typedef'ing __SIZE_TYPE__ to size_t and using size_t as the
type for memcpy's third parameter.

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.
(get_line_span_for_fixit_hint): Likewise.

above.

* 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.

Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
constants where possible).

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
