Louis Dionne 0166690401 [libc++] Remove workarounds for the lack of deduction guides in C++17
All supported compilers have supported deduction guides in C++17 for a
while, so this isn't necessary anymore.

Arthur O'Dwyer eec04092d6 [libc++] [LWG2993] reference_wrapper<T> conversion from U&&
Implement the resolution of LWG2993. Replace a deleted constructor
with a constructor that SFINAEs away in appropriate circumstances.
Also, now that the constructor is templated, we must have an
explicit deduction guide to make CTAD work.

Some tests have been merged in from Agustín Bergé's D40259.
