arc/gcc: Better creation of __NPS400__ define

The __NPS400__ define is currently created in CPP_SPEC unlike the other
target defines, which are created in arc-c.def.  Further, the current
__NPS400__ define is (currently) only created when -mcpu=nps400 is
passed, which is fine, except that if GCC is configured using
--with-cpu=nps400 then the -mcpu option is not required and the
__NPS400__ define will not be created.

This commit moves the __NPS400__ define into arc-c.def inline with all
of the other target defines, and removes the code in CPP_SPEC that used
to create the define.

In order to support the creation of the define in arc-c.def, a new
TARGET_NPS400 macro is created in arc.h.

gcc/ChangeLog:

* config/arc/arc-c.def: Add __NPS400__ definition.
* config/arc/arc.h (CPP_SPEC): Don't define __NPS400__ here.
(TARGET_NPS400): Define.

gcc/arc: Make arc_selected_cpu global

Currently we only make the base_architecture globally available, this
means we can tell if we have selected arc700/archs/etc but it's not
possible to tell if the user has selected a specific cpu variant, for
example nps400.

One problem this causes is, for example, in arc-c.def, if we want to add
an __NPS400__ define then we need a flag we can check to determine if
this is the right thing to do.

In this commit the arc_selected_cpu variable (previously local within
arc.c) has been made global.  Two other variables arc_base_cpu and
arc_selected_arch have been deleted, all of this information can be
found within (or through) arc_selected_cpu.

All uses of arc_base_cpu and arc_selected_arch have been updated.  This
commit does not introduce any new defines (like __NPS400__), this is
just a restructuring commit.

The declaration of arc_selected_cpu has moved into arc-arch.h, in
contrast to the declaration of arc_base_cpu which was previously in
arc.h.  This avoids a compilation issue when building libgcc, as the
structure and enums declared in arc-arch.h are not included for libgcc
then declaring an arc_selected_cpu (a struct type) in arc.h would result
in an unknown struct error.  We got away with this for arc_base_cpu as
that was an enum type.  The declaration of arc_selected_cpu in
arc.h could have been wrapped in a '#ifndef IN_LIBGCC2 ... #endif', but
it felt neater to simply move the declaration into arc-arch.h.

* config/arc/arc-arch.h (arc_arch_t): Move unchanged to earlier in

* tree-vrp.c (simplify_div_or_mod_using_ranges): If op1 is not
constant, but SSA_NAME with a known integer range, use the minimum
of that range instead of op1 to determine if modulo can be replaced
with its first operand.

* gcc.dg/tree-ssa/pr79408.c: New test.
