o no support yet for many ait_* types, although eventually most of them
shouldn't be generated at all for the llvm target
o no support yet for calling "opt" (which optimises llvm bitcode) before
calling llc (which translates llvm bitcode into native code) -- compile
with -s and manually call "opt" with -std-compile-opts, -O1, -O2 or -O3
if you want to experiment
o override the assembler writer with the llvm one when compiling an llvm-
targeting compiler
o override the assembler file extension with .ll when compiling an llvm-
targeting compiler
