Nemanja Ivanovic f1746be666 [Sanitizers] Fix test case that doesn't clean up after itself 
Commit https://reviews.llvm.org/rG144e57fc9535 added this test
case that creates message queues but does not remove them. The
message queues subsequently build up on the machine until the
system wide limit is reached. This has caused failures for a
number of bots running on a couple of big PPC machines.

This patch just adds the missing cleanup.

Alex Richardson aa85c6f2a5 [compiler-rt] Fix atomic support functions on 32-bit architectures 
The code currently uses __c11_atomic_is_lock_free() to detect whether an
atomic operation is natively supported. However, this can result in a
runtime function call to determine whether the given operation is lock-free
and clang generating a call to e.g. __atomic_load_8 since the branch is
not a constant zero. Since we are implementing those runtime functions, we
must avoid those calls. This patch replaces __c11_atomic_is_lock_free()
with __atomic_always_lock_free() which always results in a compile-time
constant value. This problem was found while compiling atomic.c for MIPS32
since the -Watomic-alignment warning was being triggered and objdump showed
an undefined reference to _atomic_is_lock_free.

In addition to fixing 32-bit platforms this also enables the 16-byte case
that was disabled in r153779 (185f2edd70).

Rainer Orth a9cbe5cf30 [X86] Fix stack alignment on 32-bit Solaris/x86 
On Solaris/x86, several hundred 32-bit tests `FAIL`, all in the same way:

  env ASAN_OPTIONS=halt_on_error=false ./halt_on_error_suppress_equal_pcs.cpp.tmp
  Segmentation Fault (core dumped)

They segfault during startup:

  Thread 2 received signal SIGSEGV, Segmentation fault.
  [Switching to Thread 1 (LWP 1)]
  0x080f21f0 in __sanitizer::internal_mmap(void*, unsigned long, int, int, int, unsigned long long) () at /vol/llvm/src/llvm-project/dist/compiler-rt/lib/sanitizer_common/sanitizer_solaris.cpp:65

  (gdb) p/x $esp
  $3 = 0xfeffd488

The problem is that `movaps` expects 16-byte alignment, while 32-bit Solaris/x86
only guarantees 4-byte alignment following the i386 psABI.

This patch updates `X86Subtarget::initSubtargetFeatures` accordingly,
handles Solaris/x86 in the corresponding testcase, and allows for some
variation in address alignment in
`compiler-rt/test/ubsan/TestCases/TypeCheck/vptr.cpp`.

Tested on `amd64-pc-solaris2.11` and `x86_64-pc-linux-gnu`.

mhl 66df98945e [libfuzzer] Reduce default verbosity when printing large mutation sequences 
When using a custom mutator (e.g. thrift mutator, similar to LPM)
that calls back into libfuzzer's mutations via `LLVMFuzzerMutate`, the mutation
sequences needed to achieve new coverage can get prohibitively large.

Printing these large sequences has two downsides:

1) It makes the logs hard to understand for a human.
2) The performance cost slows down fuzzing.

In this patch I change the `PrintMutationSequence` function to take a max
number of entries, to achieve this goal. I also update `PrintStatusForNewUnit`
to default to printing only 10 entries, in the default verbosity level (1),
requiring the user to set verbosity to 2 if they want the full mutation
sequence.

For our use case, turning off verbosity is not an option, as that would also
disable `PrintStats()` which is very useful for infrastructure that analyzes
the logs in realtime. I imagine most users of libfuzzer always want those logs
in the default.

I built a fuzzer locally with this patch applied to libfuzzer.

When running with the default verbosity, I see logs like this:

    #65 NEW    cov: 4799 ft: 10443 corp: 41/1447Kb lim: 64000 exec/s: 1 rss: 575Mb L: 28658/62542 MS: 196 Custom-CrossOver-ChangeBit-EraseBytes-ChangeBit-ChangeBit-ChangeBit-CrossOver-ChangeBit-CrossOver- DE: "\xff\xff\xff\x0e"-"\xfe\xff\xff\x7f"-"\xfe\xff\xff\x7f"-"\x17\x00\x00\x00\x00\x00\x00\x00"-"\x00\x00\x00\xf9"-"\xff\xff\xff\xff"-"\xfa\xff\xff\xff"-"\xf7\xff\xff\xff"-"@\xff\xff\xff\xff\xff\xff\xff"-"E\x00"-

Staring hard at the logs it's clear that the cap of 10 is applied.

When running with verbosity level 2, the logs look like the below:
