[Ada] Missing predicate check on return value
The semantics of the return statement includes an implicit conversion of
the value to the return type of the funcction. This conversion, as
elsewhere, entails a predicate check if the return type has a predicate
aspect.
We do not apply the check to a case expression because in the context of
a return statement it will be expanded into a series of return
statements, each of which will receive a predicate check.

Change EQ_ATTR_ALT to support up to 64 alternatives
On S/390 there is a need to support more than 32 instruction
alternatives per define_insn. Currently this is not explicitly
prohibited or unsupported: MAX_RECOG_ALTERNATIVES is equal 35, and,
futhermore, the related code uses uint64_t for bitmaps in most places.
However, genattrtab contains the logic to convert (eq_attr "attribute"
"value") RTXs to (eq_attr_alt bitmap) RTXs, where bitmap contains
alternatives, whose "attribute" has the corresponding "value".
Unfortunately, bitmap is only 32 bits.
When adding the 33rd alternative, this led to (eq_attr "type" "larl")
becoming (eq_attr_alt -1050625 1), where -1050625 == 0xffeff7ff. The
cleared bits 12, 21 and 32 correspond to two existing and one newly
added insn of type "larl". compute_alternative_mask sign extended this
to 0xffffffffffeff7ff, which contained non-existent alternatives, and
this made simplify_test_exp fail with "invalid alternative specified".
I'm not sure why it didn't fail the same way before, since the top bit,
which led to sign extension, should have been set even with 32
alternatives. Maybe simplify_test_exp was not called for "type"
attribute for some reason?
This patch widens EQ_ATTR_ALT bitmap to 64 bits, making it possible to
gracefully handle up to 64 alternatives. It eliminates the problem with
the 33rd alternative on S/390.

S/390 epilogue ends with (parallel [(return) (use %r14)]) instead of

This was introduced for processors older than z196, where it is

Use vectored writes when reporting errors and warnings.
When producing error and warning messages, libgfortran writes a
message by using many system calls. By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.
In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write. In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.
Regtested on x86_64-pc-linux-gnu.

* trans-expr.c (gfc_trans_assignment_1): The rse.pre for the
assignment of deferred character array vars to a realocatable
lhs should not be added to the exterior block since vector
indices, for example, generate temporaries indexed within the
loop.

Un-split hypot<long double> tests
Remove the hypot-long-double.cc file that used dg-xfail-run-if and
simply use the lower tolerance for double if long double is not larger
than double.
* testsuite/26_numerics/headers/cmath/hypot-long-double.cc: Remove.
* testsuite/26_numerics/headers/cmath/hypot.cc: Restore test for
long double unconditionally, but use lower tolerance when
sizeof(long double) == sizeof(double).
In r262891 I reimplemented this call:
dump_printf_loc (MSG_NOTE, loc, "=== %s ===\n", name);
in dump_begin_scope to use direct calls to dump_loc:
if (dump_file)
{
dump_loc (MSG_NOTE, dump_file, loc.get_location_t ());
fprintf (dump_file, "=== %s ===\n", name);
}
However ::dump_loc doesn't filter with pflags and alt_flags.
This lead to stray output of the form:
test.cpp:1:6: note: test.cpp:1:11: note:
when using -fopt-info with "optimized" or "missed".
This patch adds this missing filtering, eliminating the stray partial
note output.
