2018-07-13x86: Tune Skylake, Cannonlake and Icelake as Haswellhjl
r259399, which added PROCESSOR_SKYLAKE, disabled many x86 optimizations which are enabled by PROCESSOR_HASWELL. As the result, -mtune=skylake generates slower codes on Skylake than before. The same also applies to Cannonlake and Icelak tuning. This patch changes -mtune={skylake|cannonlake|icelake} to tune like -mtune=haswell for until their tuning is properly adjusted. It also enables -mprefer-vector-width=256 for -mtune=haswell, which has no impact on codegen when AVX512 isn't enabled. Performance impacts on SPEC CPU 2017 rate with 1 copy using -march=native -mfpmath=sse -O2 -m64 are 1.

2018-07-04PR libstdc++/86127 avoid unnecessary allocator conversionsredi
There is no need to use an allocator of the correct value_type when calling allocator_traits::construct and allocator_traits::destroy. The existing node allocator can be used, instead of constructing a new allocator object every time. There's also no benefit to using __gnu_cxx::__alloc_traits instead of std::allocator_traits to get the pointer and const_pointer types. std::forward_list is only available for C++11 and later, when std::allocator_traits is available too.

When deduction guides are supported by the compiler (i.e. for C++17 and later) replace two basic_string constructors by constrained function templates as required by LWG 3075. In order to ensure that the pre-C++17 non-template constructors are still exported from the shared library define a macro in src/c++11/string-inst.cc to force the non-template declarations (this isn't strictly needed yet, because the string instantiations are compiled with -std=gnu++11, but that is likely to change).
