Add a wi::to_wide helper function
As Richard says, we ought to have a convenient way of converting
an INTEGER_CST to a wide_int of a particular precision without
having to extract the sign of the INTEGER_CST's type each time.
This patch adds a wi::to_wide helper for that, alongside the
existing wi::to_offset and wi::to_widest.
Tested on x86_64-linux-gnu and aarch64-linux-gnu.
gcc/
* tree.h (wi::to_wide): New function.
* expr.c (expand_expr_real_1): Use wi::to_wide.
* fold-const.c (int_const_binop_1): Likewise.
(extract_muldiv_1): Likewise.
gcc/c-family/
* c-common.c (shorten_compare): Use wi::to_wide.
