As far as I know, there isn't. The gcc front-end has only been modified
to emit code in LLVM syntax, it will do whatever it regularly does,
which includes some optimizations.

The only solution I know of is to write LLVM assembly directly and then
use the LLVM assembler to make .bc files for input into opt and friends.
That will not eliminate dead code or constant-propagate.

HTH.
