a850449234 * dwarf2-frame.c (execute_cfa_program): Move DWA_CFA_nop before 
DW_CFA_def_cfa_exporession.  Add support for
DW_CFA_offset_extendend_sf, DW_CFA_def_cfa_sf and
DW_CFA_def_cfa_offset_sf.  This should fix PR backtrace/1391.

3588991722 * dwarf2-frame.c (dwarf2_reg_rule): Add REG_RA and REG_CFA. 
(dwarf2_frame_cache): Initialize PC_REGNUM with REG_RA and
SP_REGNUM with REG_CFA.  Don't overwrite the initialized register
rule for registers left unspecified by the CFI.  Remove the
special handling of PC_REGNUM.  Add code to eleminate any REG_RA
rules.
(dwarf2_frame_prev_register): Remove the special handling of
SP_REGNUM.  Add support for the REG_CFA rule.
