This reverts part of r237808.
The CMP0057 warnings came from an old development build of CMake that
nobody else has. We don't need the cruft.

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.

Without the --target flag, clang uses the mips64 triple which selects the n64 abi. We need to add --target=mips-linux-gnu, so that clang can select the correct abi for mips32r2.

Current code tries to find the dynamic TLS header to the left of the
TLS block without checking that it's not a static TLS allocation.

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.

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).

Mark longjmp tests as XFAIL because longjmp assembly for mips is not yet implemented.

This test was failing on mips because mips addresses are 40-bit long.
Using regex for address solves this issue.

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.

Summary:
Add a weak hook to be called from dfsan's custom memcmp.
The primary user will be lib/Fuzzer.
If this works well we'll add more hooks (strcmp, etc).
Test Plan: Will be covered by lib/Fuzzer tests.

dl_iterate_phdr is somewhat broken in L (see the code for details).
We add runtime OS version detection and fallback to /proc/maps on L or earlier.
This fixes a number of ASan tests on L.

They are not part of check-all :(
This change adds sized-delete operators to the version list, and disables the
hack that excluded versioned symbols from the dynamic list - this is not an
issue in this case.
