Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

Fix bug in terminator processing for uninitialized-values: simply ignore the terminator, don't reprocess it.

LiveVariables analysis now does a flow-insensitive analysis to determine what variables have their address taken; these variables are now always treated as being live.

The DataflowSolver now uses "SetTopValue()" when getting the initial value for the entry/exit block.

Bug fix in VisitChildren: Only visit the last statement in a StmtExpr and the RHS of a comma expression, as the other Stmts will be visited elsewhere in a CFGBlock.

in a block's terminator.  This expression is visited within a block, but it is accessed by the
terminator.  This is important to observe because for live-variables analysis the block-level
expression is live between the terminator and where the expression occurs in the block.  So far
this hasn't been an issue to not observe this because the block-level expression used in the
terminator is always the last one in the block, and we have never queried the liveness information
about this point (but before the terminator).
