dwarf2: Reduce some redundant definitions.
Move some definitions to defaults.h; some simply aren't needed
anymore in the respective dwarf2{cfi,out}.c files.
* defaults.h (DWARF_CIE_DATA_ALIGNMENT, DWARF_FRAME_RETURN_COLUMN,
DWARF_FRAME_REGNUM, DWARF2_FRAME_REG_OUT): Move from ...
* dwarf2cfi.c: ... here.
(PTR_SIZE, DWARF_OFFSET_SIZE, DWARF_INITIAL_LENGTH_SIZE): Remove.
(DWARF_ROUND, DWARF_CIE_ID): Remove.
* dwarf2out.c (INCOMING_RETURN_ADDR_RTX): Remove.
(DWARF2_FRAME_REG_OUT, DWARF_CIE_DATA_ALIGNMENT): Remove.
(DWARF_FRAME_RETURN_COLUMN, DWARF_FRAME_REGNUM): Remove.
