David Majnemer	4c2a0425b8	MS ABI: Implement x86_64 RTTI Summary: The RTTI scheme for x86_64 is largely the same as the one for i386. Differences are largely limited to avoiding load-time relocations by replacing pointers to RTTI metadata with the difference of that data relative to the load address of the module. Interestingly, this precludes the possibility of successfully using RTTI data from another DLL. The ImageBase reference is always relative to the current DLL.

MS ABI: Implement x86_64 RTTI

Summary:
The RTTI scheme for x86_64 is largely the same as the one for i386.

Differences are largely limited to avoiding load-time relocations by
replacing pointers to RTTI metadata with the difference of that data
relative to the load address of the module.

Interestingly, this precludes the possibility of successfully using RTTI
data from another DLL.  The ImageBase reference is always relative to
the current DLL.

[MS-ABI] Implements MS-compatible RTTI

Enables the emission of MS-compatible RTTI data structures for use with 
typeid, dynamic_cast and exceptions.  Does not implement dynamic_cast 
or exceptions.  As an artiface, typeid works in some cases but proper 
support an testing will coming in a subsequent patch.

majnemer has fuzzed the results.  Test cases included.
