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.

in dump_begin_scope to use direct calls to dump_loc:

This lead to stray output of the form:

Propagate address spaces to builtins.
At present, pointers passed to builtin functions, including atomic operators,
are stripped of their address space properties. This doesn't seem to be
deliberate, it just omits to copy them.
Not only that, but it forces pointer sizes to Pmode, which isn't appropriate
for all address spaces.
This patch attempts to correct both issues. It works for GCN atomics and
GCN OpenACC gang-private variables.

Add missing alignment checks in epilogue loop vectorisation (PR 86877)
Epilogue loop vectorisation skips vect_enhance_data_refs_alignment
since it doesn't make sense to version or peel the epilogue loop
(that will already have happened for the main loop). But this means
that it also fails to check whether the accesses are suitably aligned
for the new vector subarch.
We don't seem to carry alignment information from the (potentially
peeled or versioned) main loop to the epilogue loop, which would be
good to fix at some point. I think we want this patch regardless,

Remove constant vec_select restriction.
The vec_select operator is documented to require a const_int for the lane
selector operand, but GCN has an instruction that can select the lane at
runtime, so it seems reasonable to remove this restriction.
This patch simply replaces assertions that the operand is constant with early
exits from the optimizers. I think it's reasonable that vec_select with a
non-constant operand cannot be optimized, yet.
Also included is the necessary documentation tweak.

[AARCH64] Use STLUR for atomic_store
Use the STLUR instruction introduced in Armv8.4-a.
This instruction has the store-release semantic like STLR but can take a
9-bit unscaled signed immediate offset.
Example test case:
```
void
foo ()
{
int32_t *atomic_vals = calloc (4, sizeof (int32_t));
atomic_store_explicit (atomic_vals + 1, 2, memory_order_release);
}
```
Before patch generates
```
foo:
stp x29, x30, [sp, -16]!
mov x1, 4
mov x0, x1
mov x29, sp
bl calloc
mov w1, 2
add x0, x0, 4
stlr w1, [x0]
ldp x29, x30, [sp], 16
ret
```
After patch generates
```
foo:

mov x1, 4
mov x0, x1
mov x29, sp
bl calloc
mov w1, 2

```
We introduce a new feature flag to indicate the presence of this instruction.
The feature flag is called AARCH64_ISA_RCPC8_4 and is included when targeting
armv8.4 architecture.
We also introduce an "arch" attribute to be checked called "rcpc8_4" after this
feature flag.

On arm this is because we don't support the _Float128 type which the test uses.
This is handled in the patch by requiring a float128 target selector.
On aarch64-none-elf, a Newlib target, it fails because fabsl is not available.
long double support is known to be incomplete in newlib, and the fabsl function is not available

For these tests it means we no longer suggest anything as an alternative to "armv8-a-typo" as an "arch=" pargma value. We do still list the valid options, we just don't prefer one particular value over the others.
When I first wrote this test it wasn't with a particular architecture suggestion in mind, but rather to test that the suggestion machinery is being sanely invoked.
So this patch changes the dg-message check to treat the "did you mean...?" hunk as optional (in case the heuristics in the suggestions machinery change again).

As described in https://gcc.gnu.org/ml/gcc-patches/2018-09/msg00963.html this test generates UXTW instructions with -mabi=ilp32
because the foo* functions take pointers and store results into them. In ILP32 the callee clears the top bits with a UXTW.
This trips the scan-assembler-not UXTW test that checks that the zero_extend form of the BFXIL pattern is used, which it is.
This patch avoids this problem by not passing pointers to the results, but instead using global variables for which the foo* functions
will synthesise the address using ADRP, avoiding the UXTW instructions.
With this patch the test PASSes fully with -mabi=ilp32 and still PASSes on LP64.
