re PR middle-end/52578 (Fails to fold another size difference)

PR middle-end/52578
* fold-const.c (fold_unary_loc): Fold (T1)(T2)x to (T1)x if
the outermost conversion is a sign-change only.
(fold_binary_loc): Disregard widening and sign-changing
conversions when we determine if two variables are equal
for reassociation.
* tree-ssa-forwprop.c (combine_conversions): Fold (T1)(T2)x to
(T1)x if the outermost conversion is a sign-change only.
* gcc.dg/pr52578.c: New testcase.
