Using `sizeof(raw_context)` generates the following warning (which is
an error in ChromeOS):
```
'memset' call operates on objects of type 'MDRawContextX86' while the size
is based on a different type 'MDRawContextX86 *'
```
This commit follows the implied advice of this warning and adjusts the
expression.

This extracts the existing objdump-based disassembler engine used in
ExploitabilityLinux into a seperate reusable class, and adds support
for most common address operand formats.
This is a precursor to using DisassemblerObjdump to handle address
resolution for non-canonical address dereferences on amd64.
