For example, I've been messing around with various high performance code
in which the codebase has three versions of code in certain functions:
one that uses AltiVec intrinsics, another that uses SSE[23] intrinsics,
and plain ol' C code.

Yes, llvm handles the intrinsics just fine but what about the case when
llvm can't/won't/doesn't?

Just a thought... I'm inclined to agree with you about bytecode
versions, since one ought not be messing around with bytecode-specific
anything. But knowing whether bytecode is being emitted could be useful.
