Implement P0479R5, [[likely]] and [[unlikely]].
[[likely]] and [[unlikely]] are equivalent to the GNU hot/cold attributes,
except that they can be applied to arbitrary statements as well as labels;
this is most likely to be useful for marking if/else branches as likely or
unlikely. Conveniently, PREDICT_EXPR fits the bill nicely as a
representation.
I also had to fix marking case labels as hot/cold, which didn't work before.
Which then required me to force __attribute ((fallthrough)) to apply to the

When running the testsuite on boards that can't report an error status DejaGNU...
When running the testsuite on boards that can't report an error status
DejaGNU uses a special wrapper to print the exit code on stdout and
parses stdout to find whether an execution failed or passed.
In testcases that use "freopen (..., ..., stdout)" this special line is
printed to the alternate location described in the freopen call and
DejaGNU can't find the error code.
This results in DejaGNU using a default return status of 2 and the test
failing.
This patch skips the two testcases that use freopen on stdout when
testing a board that requires this wrapper.
Testing done by running these two tests on arm-none-eabi cross build and

Handle vectors that don't fit in an integer.
GCN vector sizes range between 64 and 512 bytes, none of which have
correspondingly sized integer modes. This breaks a number of assumptions
throughout the compiler, but I don't really want to create modes just for this
purpose.
Instead, this patch fixes up the cases that I've found, so far, such that the
compiler tries something else, or fails to optimize, rather than just ICE.

[AArch64] Fix PR62178 testcase failures
The testcase for PR62178 has been failing for a while due to the pass

This is due to Combine merging a DUP instruction with either a load
or MLA - we can't force it to prefer one over the other. However the
generated vector loop is fast either way since it generates MLA and
merges the DUP either with a load or MLA. So relax the conditions
slightly and check we still generate MLA and there is no DUP or FMOV.

[Ada] Fix small regression with others choice in array aggregate
This change is aimed at fixing a fallout of bumping the default value of
the Max_Others_Replicate parameter of the Convert_To_Positional routine.
This parameter is responsible for taming the duplication of the
expression of an others choice in an array aggregate so that it doesn't
result in a code size explosion.
Unfortunately a fine-grained control based on the analysis of the
expression is not really possible because this analysis has not been
done yet by the time the decision is made in most cases, so the usual
syntactic ambiguities of the language come into play and make the
process a bit cumbersome. For example, it is not possible to
distinguish a simple reference to a static constant declared in another
unit from a call to a parameterless function.
Therefore the change errs on the side of caution and allows the
duplication only if the expression is unambiguously static and
sufficiently simple.
For the following three aggregates, the duplication must be blocked and
the elaboration of the aggregates must be done by means of a loop:
with Q; use Q;
procedure P is
A : Arr := (others => Get_Value);
B : Arr := (others => Get_Other_Value (0));
C : Arr := (others => Q.Get_Other_Value (1));
begin
null;
end;
package Q is
type Arr is array (1 .. 32) of Integer;
function Get_Value return Integer;
function Get_Other_Value (I : integer) return Integer;

[Ada] System'To_Address not always static
System'To_Address is supposed to be static when its parameter is static.
This patch fixes a bug in which it is considered nonstatic when used as
the initial value of a variable with the Thread_Local_Storage aspect, so
the compiler incorrectly gives an error when initializing such a
variable with System'To_Address (0).

* sem_attr.adb (To_Address): Simplify setting of
Is_Static_Expression. Remove second (unconditional) call to
Set_Is_Static_Expression -- surely it's not static if the
operand is not. Initialize Static on declaration. Do not try
to fold 'To_Address, even though it's static.
* exp_attr.adb (To_Address): Preserve Is_Static_Expression.
* sinfo.ads, sem_eval.ads, sem_eval.adb (Is_Static_Expression,
Is_OK_Static_Expression, Raises_Constraint_Error): Simplify
documentation. There was too much repetition and redundancy.

[Ada] Enhance constraints propagation to ease the work of optimizers
This patch recognizes additional object declarations whose defining
identifier is known statically to be valid. This allows additional
optimizations to be performed by the front-end.
Executing:
gcc -c -gnatDG p.ads
