* tree-ssa-strlen.c (count_nonzero_bytes): Split portions of the
function where EXP is address of the bytes being stored rather than
the bytes themselves into count_nonzero_bytes_addr. Punt on zero
sized MEM_REF. Use VAR_P macro and handle CONST_DECL like VAR_DECLs.
Use ctor_for_folding instead of looking at DECL_INITIAL. Punt before
calling native_encode_expr if host or target doesn't have 8-bit
chars. Formatting fixes.
