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/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.
