In GNAT, we materialize renamings that cannot be described in standard
DWARF as synthetic variables that describe how to fetch the renamed
object. Look for "___XR" in gcc/ada/exp_dbug.ads for more details about
this convention.
In order to have a location for these variables in the debug info (GDB
requires it not to discard the variable) but also to avoid allocating
runtime space for them, we make these variable hold a DECL_VALUE_EXPR
tree. However, since GCC 7, the DWARF back-end no longer generates a
DW_AT_location attribute for those. This patch is an attempt to restore
this attribute.

arc_can_eliminate is using arc_frmae_pointer_required() which is wrong
as the frame_pointer_needed can be set on different conditions. Fix it
by calling arc_frame_pointer_needed().

If the stack pointer is needed, emit a special barrier that will prevent
the scheduler from moving stores to the frame before the stack adjustment.
For example:
[snip]
mov_s fp,sp ; frame pointer is set here
[snip]
st r1,[fp,-24] ; frame pointer is used here
[snip]
sub_s sp,sp,0x20 ; stack pointer adjusted
So we can easily see that any interrupt between the `st` and `sub`
instruction will lead to faulty code as the interrupt routine will use
a faulty sp register, and, potentially, overwriting the value stored
by 'st' instruction. Thus, adding a scheduler barrier will force the
compiler to emit the `sub` instruction before the store one.

In Ada, the Character type is supposed to be unsigned. However,
depending on the sign of C char types, GNAT can materialize it as a
signed type for code generation purposes. When this is the case, GNAT
also attach a debug type to it so it is represented as an unsigned base
type in the debug information.
This change adapts record variant parts processing in the DWARF back-end
so that when the debug type of discriminant is unsigned while
discriminant values are signed themselves, we output unsigned
discriminant values in DWARF.

* dwarf2out.c (get_discr_value): Call the get_debug_type hook on

Since the combine pass canonicalises shift-add insns using plus and
ashift (as opposed to plus and mult which it previously used to do), it
no longer creates *add_n or *sub_n insns, as the patterns match plus and
mult only. The outcome of this is that some opportunities to generate
add{1,2,3} and sub{1,2,3} instructions are missed.
This change adds additional *add_n and *sub_n insns that match the
plus-ashift pattern. The original *add_n and *sub_n insns are still left
in, as they are sometimes generated later on by constant propagation.
The idea of adding these insns is modelled on the changes in:
https://gcc.gnu.org/ml/gcc-patches/2015-05/msg01882.html
which addresses a similar issue for the PA target.
For the small test cases that are added, even if the combine pass misses
the opportunity to generate addN or subN, constant propagation manages
to do so, so the rtl of the combine pass is checked.

* config/arc/arc.c (arc_print_operand): Handle constant operands.
