David Majnemer ed9abe119b [ConstantFolding] Support folding loads from a GlobalAlias 
The MSVC ABI requires that we generate an alias for the vtable which
means looking through a GlobalAlias which cannot be overridden improves
our ability to devirtualize.

Found while investigating PR20801.

Patch by Andrew Zhogin!
