arc: Use negative enter pattern instruction's offsets
The enter pattern instruction contains the necessary information for
the dwarf machinery to generate the appropriate dwarf code. This
patch is fixing the register offsets related to CFA, and adds a test.
gcc/
* config/arc/arc.cc (arc_save_callee_enter): Use negative offsets.
gcc/testsuite
* gcc.target/arc/enter-dw2-1.c: New file.
