Subzero: Build both Debug and Release version of llvm2ice.
Separate objects are built with -O0 and -O2.
Separate executables are built:
build/Release/llvm2ice - Release build
build/Debug/llvm2ice - Debug build
The executable built depends on whether the DEBUG make variable is set:
make -f Makefile.standalone
make -f Makefile.standalone DEBUG=1
The llvm2ice file in the top-level directory is always removed and symlinked to the appropriate build.
