TestCases/Posix/halt_on_error-torture.cc is flaky on sanitizer-ppc64be-linux recently

[Bill Seurer via llvm-commits]

 From some quick serial runs it looks like several of them are failing 
sometimes.

FAIL: AddressSanitizer-Unit :: 
Asan-powerpc64-with-calls-Test/AddressSanitizer.OOBRightTest (616 of 619)
FAIL: AddressSanitizer-Unit :: 
Asan-powerpc64-with-calls-Test/AddressSanitizer.SimpleStackTest (617 of 619)
FAIL: AddressSanitizer-Unit :: 
Asan-powerpc64-inline-Test/AddressSanitizer.SimpleStackTest (618 of 619)
FAIL: AddressSanitizer-Unit :: 
Asan-powerpc64-inline-Test/AddressSanitizer.OOBRightTest (619 of 619)
FAIL: AddressSanitizer-powerpc64-linux :: 
TestCases/Posix/current_allocated_bytes.cc (458 of 619)


I will investigate further.
