cmd/go: allow buildmode c-archive for gccgo on ppc64
In buildmodeinit, the c-archive buildmode is flagged as invalid
on linux/ppc64 for gccgo when it should be valid. This happens
because the check against the gccgo flag is done after the checks
for valid GOOS/GOARCH pairs instead of before as is done for all
other buildmode cases in this switch. This corrects the problem and
allows several of the gccgo gotools testcases to pass on linux/ppc64.

[Ada] A task not executing an entry call consumes an Entry_Call slot
This patch resolves the issue where the ATC Level of a task's first
Entry_Call slot corresponds to a task not currently making an entry
call. Consequently, the first slot is never used to record an entry
call. To resolve this, the ATC Level of a such a task is now one less
than the first index of the Entry_Call array (and as result, the ATC
level corresponding to a completed task is now two less than the first
index of this array).
To aid the maintainability of code using ATC levels new constants are
introduced to represent key ATC nesting levels and comments are
introduce for the ATC level definitions.
As a result of this change, the GNAT Extended Ravenscar Profile now
works with the full runtime. The restricted runtime had assumed that the
first Entry_Call slot would be the only slot used for entry calls and
would only initialise this slot (and
System.Tasking.Protected_Objects.Single_Entry was coded this way).
However, Extended Ravenscar uses the native implementation of
System.Tasking.Protected_Objects where this assumption doesn't hold
until the implementation of this patch. Aside from enabling an extra
nested level, this is main functional change of this patch.

Initialize backtrace state once

Calling this function allocates resources that can not be freed.
There is no backtrace_free_state function. The state is used to
cache information that is expensive to recompute. Programs are
expected to call this function at most once and to save the return

So instead of calling backtrace_create_state every time we wish to
show a backtrace, do it once and store the result in a static

[RS6000] num_insns_constant ICE
This patch came about from investigating an ICE that appeared when I
was retesting an old half-baked patch of mine to rs6000_rtx_costs.
If a const_double is fed to rs6000_is_valid_and_mask and from there to
rs6000_is_valid_mask where INTVAL is used, gcc will ICE.
The num_insns_constant ICE was introduced with git commit
f337168d97.
However, the code was buggy before that. There was no point in
testing for a mask since the mask predicates only handle const_int.
In fact, I don't think the function ever handled floating point
constants that might match a load of minus one and mask. It does now.
I've added a few comments regarding splitters so the next person
looking at this code can see how this works.
The patch also extracts code out of num_insns_constant that needed to
handle multiple gprs for DFmode constants in 32-bit mode, to a
function that handles multiple gprs a little more generally. I don't
think there is any need for anything but the 32-bit DFmode case
currently, but this allows for possible future uses. The
CONST_WIDE_INT case is also not used currently, and needed fixing.
Adding CONST_WIDE_INT_NUNITS - 1 only makes sense if the elements of
the array were being shifted into a register of size larger than the
element size (which is 64-bits).

Support instrumenting returns of instrumented functions
When instrumenting programs using __fentry__ it is often useful
to instrument the function return too. Traditionally this
has been done by patching the return address on the stack
frame on entry. However this is fairly complicated (trace
function has to emulate a stack) and also slow because
it causes a branch misprediction on every return.
Add an option to generate call or nop instrumentation for
every return instead, including patch sections.
This will increase the program size slightly, but can be a
lot faster and simpler.
This version only instruments true returns, not sibling

(sparc_pass_by_reference): Move around.
(traverse_record_type): Change offset from HOST_WIDE_INT to int.
(classify_registers): Likewise for bitpos.
(function_arg_slotno): Remove dead test and tweak comments.
<MODE_RANDOM>: Remove useless assertion and test whether the
parameter is named in order to pass it in FP registers. Return
the regno for floating-point vector types.

and use CEIL_NWORDS to compute the number of registers.
(function_arg_union_value): Minor tweaks.
(function_arg_vector_value): Add slotno and named parameters, use
CEIL_NWORDS to compute the number of registers.
(sparc_function_arg_1): Rework handling of vector types. Change
size from HOST_WIDE_INT to int.
(sparc_arg_partial_bytes): Rework handling of 32-bit ABI and deal
with vector types for the 64-bt ABI.
