* fold-const.c (fold) <TRUNC_MOD_EXPR>: Optimize unsigned modulus
by a power of two into a bit-wise AND, i.e. "X % C" as "X & (C-1)".
Normalize "X % C" as "X % -C" for signed modulus and negative C.
Optimize "X % -Y" as "X % Y" for signed modulus.
<EQ_EXPR>: Recursively call "fold" when transforming "(X % Y) == 0"
into "((unsigned) X % Y) == 0".
