Manman Ren 9491a0e190 [Global Opt] get ready to replace GlobalAddrInst with SILGlobalAddrInst. ...

We add two more fields to SILGlobalVariable: a VarDecl and a flag to see if this
is a declaration. VarDecl is mainly used for debugger support, it is also used
to check if the variable is weak imported.

We also modify the serializer to serialize the extra two fields.
