* config/tc-i386.c (allow_pseudo_reg): New.
(parse_real_register): Check for NULL just once. Allow all
register table entries when allow_pseudo_reg is non-zero.
Don't allow any registers without type when allow_pseudo_reg
is zero.
(tc_x86_regname_to_dw2regnum): Replace with ...
(tc_x86_parse_to_dw2regnum): ... this.
(tc_x86_frame_initial_instructions): Adjust for above change.
* config/tc-i386.h (tc_regname_to_dw2regnum): Remove.
(tc_parse_to_dw2regnum): New.
(tc_x86_regname_to_dw2regnum): Replace with ...
(tc_x86_parse_to_dw2regnum): ... this.
* dw2gencfi.c (tc_parse_to_dw2regnum): New, broken out of ...
(cfi_parse_reg): ... this. Use tc_parse_to_dw2regnum. Adjust
error handling.

* i386-gen.c (process_i386_registers): Process new fields.
* i386-opc.h (reg_entry): Shrink reg_flags and reg_num to
unsigned char. Add dw2_regnum and Dw2Inval.
