We used to return `int` in `getAsInt`, while `IntInit::getValue`
returns `int64_t` and `utohexstr` needs `uint64_t`. The casting
causes the wrong hex value when printing bits value.
A field `FilterClassField` is added to `GenericTable` class, which
is an optional bit field of `FilterClass`. If specified, only those
records with this field being true will have corresponding entries
in the table.
This is extremely useful for language tooling as it allows
for providing go-to-def/find-references/etc. for many
more situations than what is currently possible.

Summary:
Previously TableGen would crash trying to print the undefined value as
an integer.

Summary:
This is essentially a rewrite of the backend which introduces TableGen
base classes GenericEnum, GenericTable, and SearchIndex. They allow
generating custom enums and tables with lookup functions using
separately defined records as the underlying database.
Also added as part of this change:
- Lookup functions may use indices composed of multiple fields.
- Instruction fields are supported similar to Intrinsic fields.
- When the lookup key has contiguous numeric values, the lookup
function will directly index into the table instead of using a binary
search.
The existing SearchableTable functionality is internally mapped to the
new primitives.
