V5.1B: SEGV in rtl_verify_flow_info
A reghunt revealed that this was caused by the following patch:
2007-03-02 Eric Botcazou <ebotcazou@adacore.com>
* config/alpha/alpha.c (alpha_gp_save_rtx): Insert the insns at the
entry by means of emit_insn_at_entry.
Since alpha_gp_save_rtx is only used with TARGET_LD_BUGGY_LDGP, which is
only defined in osf5.h, alpha-dec-osf5.1b is affected while
alpha-dec-osf4.0f is not.
