LLVM representation consists of two stages - layout independent
intermediate representation gallivm_ir and driver specific
gallivm_prog. TGSI is first being translated into gallivm_ir
after that driver can set number of options on gallivm_ir and
have it compiled into gallivm_prog. gallivm_prog can be either
executed (assuming there's LLVM JIT backend for the current
target) or machine code generation can be done (assuming there's
a LLVM code generator for thecurrent target)
