runtime: make NumGoroutine wait for system goroutines to register
In libgo system goroutines register themselves after they start.
That means that there is a small race between the goroutine being
seen by the scheduler and the scheduler knowing that the goroutine
is a system goroutine. That in turn means that runtime.NumGoroutines
can overestimate the number of goroutines at times.
This patch fixes the overestimate by counting the number of system
goroutines waiting to start, and pausing NumGoroutines until those
goroutines have all registered.
This is kind of a lot of mechanism for this not very important

to the function code to a Go function value. That is done by setting
the value of a func local variable using unsafe.Pointer. The local

local variable to avoid generating a write barrier.
A write barrier is never needed here. Also, for deferreturn, we must

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.

Mark symbols as constant
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.

[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 .
