is that it is a fixed void* value that points to an memory address that remains
valid throughout the remainder of the lifetime of the SymbolManager.

I updated the Win32 versions of these APIs, but can't test them.
If there are any problems, I'd be happy to fix them as well.

was uncovered by the recent x86 EFLAGS optimization. Before

Do not abort on failure to resolve an external symbol when using dlsym stubs,

Partial fix for <rdar://problem/6645157> [clang on Xcode; regression]: error: instance variable 'someField' is private.

A recent regression caused by http://llvm.org/viewvc/llvm-project?rev=65912&view=rev.

This commit isn't fully baked. Nevertheless, it should cause Xcode to compile again. Will speak with Fariborz offline.
