[patch][PR10367] Fix the design of GlobalAlias v2

[Rafael Espíndola]

Starting a new thread to get a fresh view of the state of the patches.

The introduction of GlobalObject was already committed. These patches are
* rebased on top of trunk.
* include the feedback from the previous code review. Let me know if I
missed anything.
* Splits the manual removal of getAliasedGlobal to a separate patch.
* Includes some linker fixes I found while rereading the previous version.

One thing that I noticed with the discussion about the C api is that
LLVMAddAlias should probably not be changed, even if the constructor
of GlobalAlias is changed. I will try to split this into an
independent patch.

Cheers,
Rafael
