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.

	* passes.c (rest_of_decl_compilation): Skip call to the

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]);
}

to:
        ldr     s0, [x0, 4]
        dup     v0.4s, v0.s[0]
        str     q0, [x1]
        ldr     s0, [x0, 8]
        dup     v0.4s, v0.s[0]
        str     q0, [x1, 16]
        ret

    gcc/
	* config/aarch64/aarch64-simd.md (aarch64_simd_dup):
	Swap alternatives, make integer dup more expensive.

Aarch64_legitimate_constant_p currently returns false for symbols,
eventhough they are always valid constants.  This means LOSYM isn't
CSEd correctly.  If we return true CSE works better, resulting in
smaller/faster code (0.3% smaller code on SPEC2006).  Avoid this
for TLS symbols since their sequence is complex.

    gcc/
	* config/aarch64/aarch64.c (aarch64_legitimate_constant_p):
	Return true for non-tls symbols.

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 .
