It a first glance, it looks like this is because

DwarfException::~DwarfException() {
delete ExceptionTimer;
}

is never being called (lib/CodeGen/AsmPrinter/DwarfException.cpp).

@ahatanaka
[compiler-rt][builtins] Enable more warnings in add_security_warnings (…
8e80784 
…llvm#5320)

Enable -Wsizeof-array-div and -Wsizeof-pointer-divcompiler.

Also, replace -Wmemset-transposed-args with -Wsuspicious-memaccess. The
latter automatically enables the former and a few other warnings.
