aarch64: Add debugging information

Browse Source 
This patch enables DWARF and allows compilation with debugging
information by using "gcc -g". The unwind info is disabled for
the moment and will be revisited after SEH implementation for
the target.

gcc/ChangeLog:

	* config/aarch64/aarch64.cc (TARGET_ASM_UNALIGNED_HI_OP):
	Enable DWARF.
	(TARGET_ASM_UNALIGNED_SI_OP): Likewise.
	(TARGET_ASM_UNALIGNED_DI_OP): Likewise.
	* config/aarch64/cygming.h (DWARF2_DEBUGGING_INFO): Likewise.
	(PREFERRED_DEBUGGING_TYPE): Likewise.
	(DWARF2_UNWIND_INFO): Likewise.
	(ASM_OUTPUT_DWARF_OFFSET): Likewise.
