gcc-4.7~svn174320 fails to bootstrap

Hi Richard, Ramana. FYI, trunk currently fails to bootstrap on ARM:

../../../gcc-4.7~/libcpp/expr.c: In function 'cpp_num_sign_extend': ../../../gcc-4.7~/libcpp/expr.c:1321:1: error: could not split insn (insn:TI 53 49 92 6 (set (reg:DI 10 sl [orig:151 num$high ] [151]) (ior:DI (not:DI (reg:DI 2 r2 [171])) (reg:DI 10 sl [orig:151 num$high ] [151]))) ../../../gcc-4.7~/libcpp/expr.c:1310 869 {orndi3_neon} (nil)) ../../../gcc-4.7~/libcpp/expr.c:1321:1: internal compiler error: in final_scan_insn, at final.c:2723
