I merged trunk at 188913 into lra branch. Some changes were required to make
lra branch bootstrapped on x86/x86-64 and ppc.

* lra.c (check_rtl): Add arg to insn_invalid_p call.

ira_class_hard_regs_num instead of ira_available_class_regs.
(reload_pseudo_compare_func): Ditto.

first. Transfer true for context_p only when base_reg_loc is
defined. Add processing UNSPEC.

(equiv_address_substitution): Add arg to plus_constant calls.
(curr_insn_transform): Don't process addresses for operators.
Change duplication updates.
(inherit_reload_reg): Use ira_class_hard_regs_num instead of
ira_available_class_regs.
