Change subject: IMPALA-11223: Use unique id to create codegen instances
......................................................................


Patch Set 1:

Thanks Quanlong, this seems good to me.

I wonder if this solves a problem I've come across a few times in the past: 
when I was looking for a codegen'd function in the unoptimised llvm bitcode, 
sometimes when I ran the same query several times, the function only showed up 
in about 1 case out of 5. Do you think it's possible that the output file was 
overwritten by another fragment? Or is this change only relevant for the asm 
output?
