[LLVMdev] TableGen backend support to express relations between instruction

[Jyotsna Verma]

Hi Jakob,

Here is the first draft of the patch to add TableGen backend support for the
instruction mapping tables. Please take a look and let me know your
suggestions. As of now, I create one mapping table per relation which
results into a long .inc file. So, I'm planning to combine everything into a
single table and will include APIs (one per relation) to query from this
table. 

Thanks,
Jyotsna

Sounds good. I've started adding TableGen backend support to emit
relationship table into a .inc file. Hoping to finish it soon. 

Thanks for all your help.

You just start from getValueAsListInit() and go from there.
