Refactored LiveVariables to use getTerminatorCondition() in VisitTerminator().
Bug fix: CFG now computes Block-level expression numbers using information
from block terminators. This fixes <rdar://problem/5868189>.

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.

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).

lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
