As promised at Cauldron, this patch uses %T and %G with dump_printf and
dump_printf_loc calls to eliminate calls to

  dump_generic_expr (MSG_*, arg, TDF_SLIM)  (via %T)

and

  dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0)  (via %G)

throughout the middle-end, simplifying numerous dump callsites.

A few calls to these functions didn't match the above pattern; I didn't
touch these.  I wasn't able to use %E anywhere.

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.

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:
	stp	x29, x30, [sp, -16]!
	mov	x1, 4
	mov	x0, x1
	mov	x29, sp

	stlur	w1, [x0, 4]
	ldp	x29, x30, [sp], 16

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.

This new test has some difficulties on the fabsl function.
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 targets where long double is larger than a double.
Therefore this patch skips the test on such targets.

These two tests started failing after commit r264335 that adjusted the cutoff point at which the diagnostic suggestions machinery decides a suggestion is meaningful.
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).

With this patch the two tests PASS again on aarch64.

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.

This patch updates the pure virtual function range_label::get_text
(and its implementations) so that the index of the range is passed
in, allowing for one label instance to be shared by multiple ranges.

	* c-format.c (range_label_for_format_type_mismatch::get_text):
	Update for new param.
