than gen_rtx_PLUS to form the sum.
* explow.c (force_reg): Rearrange to not allocate new pseudo

(simplify_plus_minus): New argument force; update
all callers. Don't split CONST unless we can do something with it,
and wouldn't lose the constness of the operands.

current_function_stdarg / TARGET_SH5 instead of
current_function_anonymous_args.
* sh64.h (TARGET_VERSION): Define.
Fix comments that to refer to SH architecture -
the architecture is no longer exclusive to Hitachi.
