Fix or suppress GCC warnings during build.
Summary:
Currently a number of GCC warnings are emitted when building libc++. This patch fixes or ignores all of them. The primary changes are:
* Work around strict aliasing issues in `typeinfo::hash_code()` by using __attribute__((may_alias)). However I think a non-aliasing `hash_code()` implementation is possible. Further investigation needed.
* Add `_LIBCPP_UNREACHABLE()` to switch in `strstream.cpp` to avoid -Wpotentially-uninitialized.
* Fix -Wunused-value warning in `__all` by adding a void cast.
* Ignore -Wattributes for now. There are a number of real attribute issues when using GCC but enabling the warning is too noisy.
* Ignore -Wliteral-suffix since it warns about the use of reserved identifiers. Note Only GCC 7.0 supports disabling this warning.
* Ignore -Wc++14-compat since it warns about the sized new/delete overloads.

[libcxx] Fix a bug in strstreambuf::overflow.
The end pointer should point to one past the end of the newly allocated
buffer.

Fix various undefined behavior found by UBSan.
* Fix non-null violation in strstream.cpp
Overflow was calling memcpy with a null parameter and a size of 0.
* Fix std/atomics/atomics.flag/ tests:
a.test_and_set() was reading from an uninitialized atomic, but wasn't
using the value. The tests now clear the flag before performing the
first test_and_set. This allows UBSAN to test that clear doesn't read
an invalid value.
* Fix std/experimental/algorithms/alg.random.sample/sample.pass.cpp
The tests were dereferencing a past-the-end pointer to an array so that
they could do pointer arithmetic with it. Instead of dereference the iterator
I changed the tests to use the special 'base()' test iterator method.
* Add -fno-sanitize=float-divide-by-zero to suppress division by zero UBSAN diagnostics.
The tests that cause float division by zero are explicitly aware that they
are doing that. Since this is well defined for IEEE floats suppress the warnings
for now.

Patch from GM to make more implicit bools explicit since we can't stop MSVC warning about this in headers and to warn is the MSVC default. No functionality change.

Changed __config to react to all of clang's currently documented has_feature flags, and renamed _LIBCPP_MOVE to _LIBCPP_HAS_NO_RVALUE_REFERENCES to be more consistent with the rest of the libc++'s flags, and with clang's nomenclature.
