    unsigned long x = 1UL << b;

DWARF: make it possible to emit debug info for declarations only

The DWARF back-end used to systematically ignore file-scope function and
variable declarations.  While this is justified in language like C/C++,
where such declarations can appear in several translation units and thus
bloat uselessly the debug info, this behavior is counter-productive in
languages with a well-defined module system.  Specifically, it prevents
the description of imported entities, that belong to foreign languages,
making them unavailable from debuggers.

Take for instance:

    package C_Binding is
        function My_C_Function (I : Integer) return Integer;
        pragma Import (C, My_C_Function, "my_c_function");
    end C_Binding;

This makes available for Ada programs the C function "my_c_function"
under the following name: C_Binding.My_C_Function.  When GCC compiles
it, though, it is represented as a FUNCTION_DECL node with DECL_EXTERNAL
set and a null DECL_INITIAL, which used to be discarded unconditionally
in the DWARF back-end.

This patch moves such filter from the DWARF back-end to the relevant
callers: passes.c:rest_of_decl_compilation and
godump.c:go_early_global_decl. It also This patch also updates the Ada
front-end to call debug hooks for functions such as in the above
example, so that we do generate debugging information for them.

Improve dup pattern

Improve the dup pattern to prefer vector registers.  When doing a dup
after a load, the register allocator thinks the costs are identical
and chooses an integer load.  However a dup from an integer register
includes an int->fp transfer which is not modelled.  Adding a '?' to
the integer variant means the cost is increased slightly so we prefer
using a vector register.  This improves the following example:

#include <arm_neon.h>
void f(unsigned *a, uint32x4_t *b)
{
  b[0] = vdupq_n_u32(a[1]);
  b[1] = vdupq_n_u32(a[2]);

[Patch AArch64] Add initial tuning support for Cortex-A55 and Cortex-A75

This patch adds support for the ARM Cortex-A75 and
Cortex-A55 processors through the -mcpu/-mtune values cortex-a55 and
cortex-a75, and an ARM DynamIQ big.LITTLE configuration of these two
processors through the -mcpu/-mtune value cortex-a75.cortex-a55

The ARM Cortex-A75 is ARM's latest and highest performance applications
processor. For the initial tuning provided in this patch, I have chosen to
share the tuning structure with its predecessor, the Cortex-A73.

The ARM Cortex-A55 delivers the best combination of power efficiency
and performance in its class. For the initial tuning provided in this patch,
I have chosen to share the tuning structure with its predecessor, the
Cortex-A53.

Both Cortex-A55 and Cortex-A75 support ARMv8-A with the ARM8.1-A and
ARMv8.2-A extensions, along with the cryptography extension, and
the RCPC extensions from ARMv8.3-A. This is reflected in the patch,
-mcpu=cortex-a75 is treated as equivalent to passing -mtune=cortex-a75
-march=armv8.2-a+rcpc .
