First attempt at a patch

The attached patch makes the v850 build on x86_64. There are a few regressions
(when run on i686-pc-linux-gnu):

+FAIL: gcc.c-torture/compile/pr23233-1.c  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  (internal compiler error)
+FAIL: gcc.c-torture/compile/pr23233-1.c  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  (test for excess errors)
+FAIL: gcc.c-torture/compile/pr29250.c  -O3 -fomit-frame-pointer -funroll-loops
 (internal compiler error)

line 16)
+FAIL: g++.dg/opt/asm1.C double sized union element should be addressible (test
for bogus messages, line 8)
+FAIL: g++.dg/opt/pr15551.C execution test
