Comment (by angerman):

 That's a fantastic idea!

 I guess we could even name the initial block `entry`, and just allocate
 all the registers on the stack and just fall through into the first block.
 I'll give this a try with the `llvmng`. If this works, I might backport it
 to the `llvm` backend. It would also relinquish the need for the unique
 supply in the `LlvmM` I believe.
