+       * fold-const.c (sign_bit_p): Return EXP if VAL is the sign bit
+       of HOST_WIDE_INT.
+       (fold_single_bit_test): If sign_bit_p() fails, assume that the
+       bit being tested is not a sign bit.

+       * expr.c (do_store_flag): Remove special case folding for
+       single bit tests.  Instead call back into the commonized folder
+       routine.
+       * fold-const.c (fold_single_bit_test): New function, mostly
+       extracted from do_store_flag, with an additional case extracted
+       from fold.
+       (fold): Call fold_single_bit_test appropriately.
+       * tree.h (fold_single_bit_test): Prototype.
