Matt Arsenault 4af0733112 TableGen: Handle nontrivial foreach range bounds
This allows using anything that isn't a literal integer as the bounds
for a foreach. Some of the diagnostics aren't perfect, but nobody ever
accused tablegen of having good errors. For example, the existing
wording suggests a bitrange is valid, but as far as I can tell this
has never worked.

Fixes bug 41958.
