Evgeniy Stepanov bab1a075df [asan] Add new(unsigned int) to ASan interface list.
Also, sized-delete with size_t == unsigned int.
These guys appear when building for Android with gnu-stl.

Fixes a number of ASan tests in that particular configuration.

Evgeniy Stepanov 1f1d9f27fd [asan] Fix build dependency issues with ASan version list file.
CMake pre-3.1 has a bug where a shared library depending on a custom_target
does not really depend on it.

This commit implements a hilariously ugly workaround for this problem, see
code comments for more details.

Evgeniy Stepanov 45328240dc [msan] Mprotect all inaccessible memory regions.
Fix 2 bugs in memory mapping setup:
- the invalid region at offset 0 was not protected because mmap at
  address 0 fails with EPERM on most Linux systems. We did not
  notice this because the check condition was flipped: the code was
  checking that mprotect has failed. And the test that was supposed
  to catch this was weakened by the mitigations in the mmap
  interceptor.
- when running without origins, the origin shadow range was left
  unprotected.

The new test ensures that mmap w/o MAP_FIXED always returns valid
application addresses.

Saleem Abdulrasool a3b3952ccd builtins: mark functions as aapcs on Windows
Windows does not use AAPCS, but rather AAPCS-VFP, and thus the functions which
are assumed to be AAPCS will cause invalid argument setup.  Ensure that the
functions are marked as AAPCS.

Reid Kleckner aa9029691f Silence some CMake 3.3 dev warnings in compiler-rt
Fix a trivial instance of CMP0054 that came up on llvmdev.

The other warnings were CMP0057, which is about using the same file as a
MAIN_DEPENDENCY multiple times.  The old behavior hasn't been a problem
yet, so I silenced the warning and filed PR23595 to document the issue
if someone cares.

Ahmed Bougacha 9a43d5be2f [Builtins] Implement f2h/h2f by jumping to trunc/extend.
Follow-up to r237161; seems like we can't use aliases, but we
can do better than duplicating the bodies, especially when that
body, after inlining, isn't as small as it looks.

Better approaches welcome.  Perhaps the best thing is just to have
an #ifndef __APPLE__ over the GNUEABI names, since they're not used
there.

Ahmed Bougacha f1ac850e77 [Builtins] Implement half-precision conversions.
Mostly uninteresting, except:
- in __extendXfYf2, when checking if the number is normal, the old
  code relied on the unsignedness of src_rep_t, which is a problem
  when sizeof(src_rep_t) < sizeof(int): the result gets promoted to
  int, the signedness of which breaks the comparison.
  I added an explicit cast; it shouldn't affect other types.
- we can't pass __fp16, so src_t and src_rep_t are the same.
- the gnu_*_ieee symbols are simply duplicated definitions, as aliases
  are problematic on mach-o (where only weak aliases are supported;
  that's not what we want).

Justin Bogner fa7525935b builtins: Implement the functions from stdatomic.h
Talking to John and Doug, we concluded that these functions from
stdatomic really do belong here in compiler-rt rather than in libc,
since the compiler owns stdatomic.h and these need to refer to
clang-specific builtins. Nonetheless, I've only added these on darwin
for now - other platforms should probably do the same unless their
libc does implement these functions.
