Backport fix to set mips_dbx_regno entries to IGNORED_DWARF_REGNUM by default
2012-12-12 Steve Ellcey <sellcey@mips.com>
* config/mips/mips.c (mips_option_override): Set
mips_dbx_regno entries to IGNORED_DWARF_REGNUM by default.

PR target/54061
rtl.h (IGNORED_DWARF_REGNUM): New.
* dwarf2out.c (reg_loc_descriptor): Check for IGNORED_DWARF_REGNUM.
(mem_loc_descriptor): Ditto.
* config/mips/mips.h (ALL_COP_REG_FIRST): New.
(ALL_COP_REG_LAST): New.
(ALL_COP_REG_NUM): Redefine using above macros.
* config/mips/mips.c (mips_option_override): Set mips_dbx_regno
coprocessor entries to IGNORED_DWARF_REGNUM.
