- Split backend related consumer out into Backend.cpp, replaces
LLVMCodeGenWriter.
- Structure follows llvm-gcc to some extent.
- Still need to implement all the options which impact code
generation and the optimization passes which llvm-gcc uses at
various levels.

Make target info available to clang code generator. This is far from complete but this helps clang codegen module make progress.
At the moment target triplet and target description strings are hard coded in clang::TargetInfo

to variables that are no longer live. This analysis is built on top
of CFGs and the LiveVariables analysis.
changes to driver:
added driver option "-check-dead-stores" to run the analysis

source-level CFGs. This code may change significantly in the near
future as we explore different means to implement dataflow analyses.
Added a driver option, -dump-live-variables, to view the output of
live variable analysis. This output is very ALPHA; it will be improved shortly.
