Eric Fiselier a60d7fac09 Add diagnostics for min/max algorithms when a InputIterator is used. 
These algorithms require a ForwardIterator or better. Ensure
we diagnose the contract violation at compile time instead of
of silently doing the wrong thing.

Further algorithms will be audited in upcoming patches.

Peter Collingbourne 939b16233b Fix the BinaryPredicate form of std::is_permutation to not rely on operator== 
According to [1], forms 2 and 4 of std::is_permutation should use the passed in
binary predicate to compare elements. operator== should only be used for forms
1 and 3 which do not take a binary predicate.

This CL fixes forms 2 and 4 which relied on operator== for some comparisons.

Eric Fiselier decf22e50f Fix most GCC test failures. 
This patch fixes almost all currently failing tests when
using GCC ToT.

The specific changes are:

(A) Workaround gcc.gnu.org/PR83921 which rejects variables w/o initializers
in constexpr contexts -- even when the variable is an empty class. This
bug has been worked around at all callsites by adding an initializer.
Additionally a new test, constexpr_init.pass.cpp, has been added to
test that Clang doesn't suffer from these bugs.

(B) Fix streambuf.assign/swap.pass.cpp. This test was never actually
calling the swap method as intended. In fact, the swap function it
intended to call was ill-formed when instantiated. GCC diagnosed
this ill-formedness w/o needing an instantiation.

(C) size_delete11.pass.cpp was fixed by adding c++2a to the list of
unsupported dialects.

Stephan T. Lavavej 79e0733c20 [libcxx] [test] Fix MSVC warnings, null pointer deref. 
test/std/algorithms/alg.modifying.operations/alg.generate/generate_n.pass.cpp
Silence MSVC warning C4244. This is expected when passing
floating-point values for size.

test/std/utilities/template.bitset/bitset.members/to_ullong.pass.cpp
test/std/utilities/template.bitset/bitset.members/to_ulong.pass.cpp
Avoid MSVC "warning C4293: '<<': shift count negative or too big,
undefined behavior". MSVC sees (1ULL << N) and warns - being guarded
by const bool canFit is insufficient. A small change to the code
avoids the warning without the need for a pragma.

Remove a spurious printf() declaration from to_ullong.pass.cpp.

Change ULL to UL in to_ulong.pass.cpp. The ULL suffix was
probably copy-pasted.

test/std/utilities/tuple/tuple.general/ignore.pass.cpp
Use LIBCPP_STATIC_ASSERT for consistency with other files.

test/support/container_test_types.h
Fix a null pointer dereference, found by MSVC /analyze
warning C6011 "Dereferencing NULL pointer 'm_expected_args'."

Fixes D41030.
