Move vector_type_mode to tree.c
...so that it's possible to use TYPE_MODE in tree.h.
2017-08-21 Richard Sandiford <richard.sandiford@linaro.org>
gcc/
* stor-layout.h (vector_type_mode): Move to...
* tree.h (vector_type_mode): ...here.
* stor-layout.c (vector_type_mode): Move to...
* tree.c (vector_type_mode): ...here. Include rtl.h and regs.h.
