Louis Dionne 3557c7c122 [libc++] Remove workarounds for [[nodebug]] not working properly on typedefs in older Clangs
Clang used to support [[nodebug]] everywhere except on typedefs. Since
we don't support such old Clangs anymore, we can get rid of _LIBCPP_NODEBUG_TYPE
in favour of always using _LIBCPP_NODEBUG.

Louis Dionne 64184b4af0 [libc++][NFC] Remove useless _LIBCPP_PUSH_MACROS
Only files that actually use min/max are required to do this dance.

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.

Louis Dionne 89a7bdb1f3 [libc++] Add the __bind_back and __compose helpers
Those are going to be used to implement range adaptors,
see D107098 for details.

Louis Dionne f599e7a789 [libc++] Refactor __perfect_forward, bind_front and not_fn
This patch fixes the constrains on the __perfect_forward constructor
and its call operators, which were incorrect. In particular, it makes
sure that we closely follow [func.require], which basically says that
we must deliver the bound arguments with the appropriate value category
or make the call ill-formed, but not silently fall back to using a
different value category.

As a fly-by, this patch also:
- Adds types __bind_front_t and __not_fn_t to make the result of
  calling bind_front and not_fn more opaque, and improve diagnostics
  for users.
- Adds a bunch of tests for bind_front and remove some that are now
  redundant.
- Adds some missing _LIBCPP_HIDE_FROM_ABI annotations.

Immense thanks to @tcanens for raising awareness about this issue, and
providing help with the = delete bits.

Arthur O'Dwyer f221d905b1 [libc++] IWYU to fix Modules complaints about _LIBCPP_ASSERT. NFCI.
This fixes all places that used _LIBCPP_ASSERT without including <__debug>.

Louis Dionne f86570cd52 [libc++] Avoid triggering warnings for implicit conversion
This started as fixing a typo in a ADDITIONAL_COMPILE_FLAGS directive
which turned out to uncover a few places where we warned about signedness
changes.

As a fly-by fix, this updates the various __advance overloads
for style consistency.

Arthur O'Dwyer 64a0241d64 [libc++] IWYU <__utility/pair.h> in <__functional/hash.h>. NFCI.
This was the only thing preventing any one of our detail headers from
compiling on its own.

Louis Dionne d03aa7d6b6 [libc++] NFCI: Remove __functional/search.h
The __search helper function was once split into __functional for circular
dependency reasons, however this is not an issue anymore now that we have
finer grained headers.

Louis Dionne 134723edd5 [libcxx] Move all algorithms into their own headers
This is a fairly mechanical change, it just moves each algorithm into
its own header. This is intended to be a NFC.

This commit re-applies 7ed7d4ccb8, which was reverted in 692d7166f7
because the Modules build got broken. The modules build has now been
fixed, so we're re-committing this.

zoecarver 7ed7d4ccb8 [libcxx][gardening] Move all algorithms into their own headers.
This is a fairly mechanical change, it just moves each algorithm into its own header. This is a NFC.

Note: during this change, I burned down all the includes, so this follows "include only and exactly what you use."
