Liu.andrew.x@gmail.com 12213a5e15 Checking for benign exceptions that trigger a minidump. 
If the exception reponsible for the crash is benign, such as a floating point
exception, we can rule out the possibility that the code is exploitable. This
CL checks for such exceptions and marks the dump as not exploitable if such an
exception is found.

Liu.andrew.x@gmail.com 440c1f79ef This CL adds support for ARM and ARM64 architectures when calculating 
exploitability ratings.

The stackwalker will now grab the instruction pointers for ARM and ARM64
architectures, so checking exploitability on ARM and ARM64 will no longer
return EXPLOITABILITY_ERR_PROCESSING.

Liu.andrew.x@gmail.com cca153368a Checking location of the instruction pointer to see if it is 
in valid code for Linux exploitability rating.

This CL adds to the Linux exploitability checker by verifying that the
instruction pointer is in valid code. Verification is done by obtaining a
memory mapping of the crash and checking if the instruction pointer lies in
an executable region. If there is no memory mapping, the instruction pointer
is checked to determine if it lies within a known module.
