PR 13503
* reloc.c: Add new ENUM for BFD_RELOC_AVR_8_LO,
BFD_RELOC_AVR_8_HI, BFD_RELOC_AVR_8_HHI.
* bfd-in2.h: Regenerate.
* libbfd.h: Regenrate.
* elf32-avr.c (elf_avr_howto_table): Add entries for
R_AVR_8_LO8, R_AVR_8_HI8, R_AVR_8_HHI8.
(avr_reloc_map): Add RELOC mappings for R_AVR_8_LO8, R_AVR_8_HI8,
R_AVR_8_HHI8.
* config/tc-avr.c (exp_mod_pm): Remove variable.
(exp_mod_data_t): New typedef.
(pexp_mod_data, exp_mod_data): New variables.
(avr_parse_cons_expression): Scan through exp_mod_data[] to find
data expression modifiers "pm", "gs", "lo8", hi8", "hhi8", "hh8"
and set pexp_mod_data accordingly to be used in avr_cons_fix_new.
(avr_cons_fix_new): Handle new data expression modifiers shipped
in pexp_mod_data.
(md_apply_fix): Handle BFD_RELOC_AVR_8_LO, BFD_RELOC_AVR_8_HI,
BFD_RELOC_AVR_8_HHI.
* elf/avr.h (RELOC_NUMBERS): Add values for R_AVR_8_LO8,
R_AVR_8_HI8, R_AVR_8_HHI8.
