* fold-const.c (tree_call_nonnegative_warnv_p): Return true
for BUILT_IN_C{LZ,LRSB}*.
* tree.h (CASE_INT_FN): Add FN##IMAX case.
* tree-vrp.c (extract_range_basic): Handle
BUILT_IN_{FFS,PARITY,POPCOUNT,C{LZ,TZ,LRSB}}*. For
BUILT_IN_CONSTANT_P if argument isn't (D) of PARM_DECL,
fall thru to code calling set_value*.
* builtins.c (expand_builtin): Remove *IMAX cases.
(fold_builtin_bitop): For BUILT_IN_CLRSB* return NULL_TREE
if width is bigger than 2*HWI.
* libgcc2.c (__floattisf): Avoid undefined signed overflow.
* gcc.dg/tree-ssa/vrp89.c: New test.
