Reapply "Merge commit e24f90190c77 from llvm git (by Brad Smith):"
[Driver] Enable outline atomics for FreeBSD/aarch64 (#156089)
The compiler_rt helper functions have been built since 12.4, 13.1, 14
and anything newer.
This reverts commit bd27bd1f51d049538cc7a0053be9d99110a53ae1.
Only some people (including the release manager, unfortunately) ran into
build issues with the previous iteration of this commit, because they
were bootstrapping the compiler, either via the WITHOUT_SYSTEM_COMPILER
src.conf(5) setting, or because the build system determined that their
base system compiler was out of date.
The bootstrapped compiler would then enable outline atomics and compile
libgcc_s with these, but because libgcc_s is linked with -nodefaultlibs,
it could not find the helper routines in libcompiler_rt.a.

nda: fix setting of unmappedio flag
The upstream refactoring of ndaregister() to split out ndasetgeom()
accidentally used an uninitialed variable to decide whether or not
to set DISKFLAG_UNMAPPED_BIO. Fix this by moving that portion of
ndasetgeom() back up to ndaregister(). The check for PIM_UNMAPPED
is not really needed because nvme devices always have that set,
so it cannot change in the other path that ndasetgeom() is now called.

fdread: Fix logic bug when reading by sector
When reading by sector (because reading a whole track failed), we can
accidentally fall into the "should not happen" path, which both
(a) emits a spurious error message and (b) fouls up our position
accounting going forward. Ensure we do not inappropriately fall into
that path.
Avoid obscuring the "short after" message in cases where it happens.

libefivar: Support UefiDevicePathLib under StandaloneMm
This change added an instance of UefiDevicePathLib for StandaloneMm. It
abstracts DevicePathFromHandle function into different files for
Standalone MM and other instances to avoid linking gBS into MM_STANDALONE
drivers.
No functional change intended, as this function and its invocation are ifdefd
out.
