Fix building libc++ with the macOS 10.13 SDK with -mmacosx-version-min=10.12 or lower.
The 10.13 SDK always defines utimensat() (with an availability(macosx=10.13) annotation)
and unconditionally defines UTIME_OMIT, so use the compile-time availability macros
on Apple platforms instead.
For people statically linking libc++, it might make sense to also provide an opt-in
option for using __builtin_available() to dynamically check for the OS version,
but for now let's do the smallest thing needed to unbreak the build.
Based on a patch by Eric Fiselier <eric@efcs.ca>: https://reviews.llvm.org/D34249
Fixes PR33469.

Fix filesystem build on platforms with weird time_t types.
32-bit powerpc provides a 64 bit time_t type and older ppc64 systems
provide time_t as a floating point type. This caused problems when building
operations.cpp since operations.cpp contained compile time tests for conversions
between time_t and filesystem time type.
When these tests failed they caused the libc++ build to fail as well. This is unfortunate.
This patch moves the tests out of the source file and into the test suite. It also
expands the tests to allow testing of the weird time_t configurations on all platforms.

Implement LWG 2937 - equivalent("dne", "exists") is not an error
This patch speculatively implements the PR for LWG 2937, which fixes
two issues with equivalent.
(1) It makes equivalent("dne", "exists") an error. Previously only
equivalent("dne", "dne") was an error and the former case was not (it returned false).
Now equivalent reports an error when either input doesn't exist.
(2) It makes equivalent(p1, p2) well-formed when `is_other(p1) && is_other(p2)`.
Previously this was an error, but there is seemingly no reason why it should be on POSIX system.

Improve 'last_write_time(...)' accuracy and detect overflow errors.
The ::stat struct on Linux, FreeBSD, and OS X provides the access and
modification times as an instance of 'timespec', which has a nanosecond
resolution. The 'st_mtime' and 'st_atime' members simply reference the 'tv_sec'
value of the timespec struct. This patch changes 'last_write_time(...)' so that
it extracts both the seconds and nanoseconds values of the last modification
time, providing a more accurate implementation of 'last_write_time(...)'.
Additionally this patch fixes a possible signed integer overflow bug. The
'file_time_type' type cannot represent all possible values returned by
the filesystem. Attempting to construct a 'file_time_type' from one of these
values is undefined behavior. This patch avoids that UB by detecting possible
overflows before the conversion.

Implement LWG issue 2720. Replace perms::resolve_symlinks with perms::symlink_nofollow.
This changes how filesystem::permissions(p, perms) handles symlinks. Previously
symlinks were not resolved by default instead only getting resolved when
"perms::resolve_symlinks" was used. After this change symlinks are resolved
by default and perms::symlink_nofollow must be given to change this.
This issue has not yet been moved to Ready status, and I will revert if it
doesn't get moved at the current meeting. However I feel confident that it
will and it's nice to have implementations when moving issues.

Fix bugs in last_write_time implementation.
* Fix passing a negative number as either tv_usec or tv_nsec. When file_time_type
is negative and has a non-zero sub-second value we subtract 1 from tv_sec
and make the sub-second duration positive.
* Detect and report when 'file_time_type' cannot be represented by time_t. This
happens when using large/small file_time_type values with a 32 bit time_t.
There is more work to be done in the implementation. It should start to use
stat's st_mtim or st_mtimeval if it's provided as an extension. That way
we can provide a better resolution.

* Temporarily print iteration sequence to see where its failing.
2) path.native.obs/string_alloc.pass.cpp
* Remove test that ::new is not called when constructing a short string
that requires a conversion. Since during the conversion global locale
objects might be constructed.
3) fs.op.funcs/space.pass.cpp
* Explicitly use uintmax_t in the implementation of space, hopefully
preventing possible overflows.
* Add additional tests that check for overflow is the calculation of the
