PR c++/71537
* fold-const-call.c (fold_const_call_1): Remove memchr handling here.
(fold_const_call) <case CFN_BUILT_IN_STRNCMP,
case CFN_BUILT_IN_STRNCASECMP>: Formatting improvements.
(fold_const_call) <case CFN_BUILT_IN_MEMCMP>: Likewise. If s2 is 0
and arguments have no side-effects, return 0.
(fold_const_call): Handle CFN_BUILT_IN_MEMCHR.
* g++.dg/cpp0x/constexpr-memchr.C: New test.
