c: Remove restrictions on declarations in 'for' loops for C2X
C2X removes a restriction that the only declarations in the
declaration part of a 'for' loop are declarations of objects with
storage class auto or register. Implement this change, making the
diagnostics into pedwarn_c11 calls instead of errors (as usual for
features added in a new standard version that were invalid code in a
previous version), so now pedwarn-if-pedantic for older standards and
diagnosed also with -Wc11-c2x-compat.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.
gcc/c/
* c-decl.cc (check_for_loop_decls): Use pedwarn_c11 for
diagnostics.
gcc/testsuite/
* gcc.dg/c11-fordecl-1.c, gcc.dg/c11-fordecl-2.c,
gcc.dg/c11-fordecl-3.c, gcc.dg/c11-fordecl-4.c,
gcc.dg/c2x-fordecl-1.c, gcc.dg/c2x-fordecl-2.c,
gcc.dg/c2x-fordecl-3.c, gcc.dg/c2x-fordecl-4.c: New tests.
* gcc.dg/c99-fordecl-2.c: Test diagnostic for typedef declaration
in for loop here.
* gcc.dg/pr67784-2.c, gcc.dg/pr68320.c, objc.dg/foreach-7.m: Do
not expect errors for typedef declaration in for loop.
