arc: Fix for loop end detection

We use a negative ID number to link together the doloop_begin and
doloop_end instructions.  This negative ID number is setup within
doloop_begin, at this point the ID is stored into the loop end
instruction (doloop_end_i) and placed into the doloop_begin_i
instruction.

In arc.c (arc_reorg) we extract the ID from the doloop_end_i
instruction in order to find the matching doloop_begin_i instruction,
though the ID is only used in some cases.

Currently in arc_reorg when we extract the ID we negate it.  This
negation is invalid.  The ID stored in both doloop_end_i and
doloop_begin_i is already negative, the negation in arc_reorg means
that if we need to use the ID to find the doloop_begin_i then we will
never find it (as the IDs will never match).

This commit removes the unneeded negation, moves the extraction of the
ID into a more appropriately scoped block and adds a new test for this
issue.

gcc/ChangeLog:

* config/arc/arc.c (arc_reorg): Move loop_end_id into a more local
block, and do not negate it, the stored id is already negative.

arc: Use @pcl assembler syntax instead of invalid expressions

The old ARC assembler would accept expressions like 'LABEL-(.&-4)'
which would calculate the offset from the PCL to LABEL.  The new ARC
assembler does not accept these expressions, instead there's an @pcl
synax, used like LABEL@pcl which gives the offset from PCL to LABEL.

Most of the use of the old expression syntax have been removed,

conflict (don't target the same base architecture).  In this case the
