Fix mismatched precisions in tree arithmetic
The tree wi:: decompose routine wasn't asserting that the requested
precision matched the tree's precision. This could make a difference
for unsigned trees that are exactly N HWIs wide and that have the upper

precisions (as for wi::to_widest).
This patch adds the assert and fixes the fallout shown by the testsuite.

[AArch64] PR71307: Define union class of POINTER+FP
ALL_REGS doesn't function as a union class of POINTER_REGS and FP_REGS
since it includes the CC register as well. REGNO_REG_CLASS (CC_REGNUM)
is NO_REGS, but of course NO_REGS rightly doesn't include CC_REGNUM.
Adding a union class for POINTER+FP allows the RA to use it as the
preferred or alternative class of a pseudo. It also works as a
union class of GENERAL+FP for modes that aren't allowed in SP.
This is also needed for the SVE port, which adds predicate registers
to the mix.

exp_ch6.adb (Expand_Call_Helper): Handle case of build-in-place functions returning nonlimited types.
2017-09-29 Bob Duff <duff@adacore.com>
* exp_ch6.adb (Expand_Call_Helper): Handle case of build-in-place
functions returning nonlimited types. Allow for qualified expressions
and type conversions.
(Expand_N_Extended_Return_Statement): Correct the computation of
Func_Bod to allow for child units.
(Expand_Simple_Function_Return): Remove assumption that b-i-p implies
limited (initialization of In_Place_Expansion), and implies >= Ada
2005.
(Is_Build_In_Place_Result_Type): New function to accompany
Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
sometimes we just have the type on our hands, not the function. For
now, does the same thing as the old version, so build-in-place is
disabled for nonlimited types, except that you can use -gnatd.9 to
enable it.
* exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
accompany Is_Build_In_Place_Function and
Is_Build_In_Place_Function_Call, because sometimes we just have the
type on our hands, not the function.
(Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
cases.
(Make_Build_In_Place_Call_In_Object_Declaration): Remove the
questionable code at the end that was setting the Etype.
* exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to
determine whether "return (...agg...);" is returning from a
build-in-place function.
(Initialize_Ctrl_Array_Component, Initialize_Ctrl_Record_Component):
Remove assumption that b-i-p implies limited (initialization of
In_Place_Expansion).
(Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
an unchecked conversion. Add assertions.
(Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
secondary stack here, just because the type needs finalization. That
code is obsolete.
(Convert_To_Assignments): Only set Unc_Decl if Nkind (N) = N_Aggregate.
For "return (...agg...);" don't assume b-i-p implies limited.
Needs_Finalization does not imply secondary stack.
(Expand_Array_Aggregate): Named notation. Reverse the sense of
Component_OK_For_Backend -- more readability with fewer double
negatives.
* exp_attr.adb (Expand_N_Attribute_Reference): Remove assumptions that
b-i-p implies >= Ada 2005.
* exp_ch3.adb (Expand_N_Object_Declaration): Remove assumptions that
b-i-p implies >= Ada 2005. Remove Adjust if we're building the return
object of an extended return statement in place.
* exp_ch4.adb (Expand_Allocator_Expression, Expand_N_Indexed_Component,
Expand_N_Selected_Component, Expand_N_Slice): Remove assumptions that
b-i-p implies >= Ada 2005.
* exp_ch5.adb (Expand_N_Assignment_Statement): Remove assumption that
b-i-p implies >= Ada 2005.
* exp_ch7.adb: Comment fix.
* exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Remove
assumptions that b-i-p implies >= Ada 2005.
* exp_disp.adb (Expand_Interface_Actuals): Remove assumptions that
b-i-p implies >= Ada 2005.
* exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
(Expr), in case Pool_Id is not set.
(Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
qualified or converted.
(Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
(Param)) = N_Identifier; that's all it could be.
* sinfo.ads: Comment fixes.
* snames.ads-tmpl: Comment fixes.
* debug.adb: Add flag gnatd.9, to enable the build-in-place machinery.

[ARM] Remove ARMv8-M code for D17-D31
Function cmse_nonsecure_entry_clear_before_return has code to deal with
high VFP register (D16-D31) while ARMv8-M Baseline and Mainline both do
not support more than 16 double VFP registers (D0-D15). This makes this
security-sensitive code harder to read for not much benefit since
libcall for cmse_nonsecure_call functions do not deal with those high
VFP registers anyway.
This commit gets rid of this code for simplicity and fixes 2 issues in
the same function:
- stop the first loop when reaching maxregno to avoid dealing with VFP
registers if targetting Thumb-1 or using -mfloat-abi=soft
- include maxregno in that loop
