prepare IR for execution in the target. Wired the expression command to use this IR transformer when conversion to DWARF fails, and wired conversion to DWARF to always fail (well, we don't generate any DWARF...) llvm-svn: 107559
block labels) and produce cleaner IR (by removing the thread-safe statics guards) llvm-svn: 107528

convert IR to DWARF. So far, this pass only performs a depth-first traversal of the IR, logging each basic block as it finds it. llvm-svn: 107515
