Manman Ren 642a0acce2 Debug Info: code clean up. ...

Remove unnecessary creation of LexicalScope in collectDeadVariables.
The created LexicialScope was only used to get isAbstractScope, which
should be false from the creation:
"new LexicalScope(NULL, DIDescriptor(SP), NULL, false);".

We can also remove a DenseMap that holds the created LexicalScopes.
