Seth Brenith 4dc1fb4e04 Revert "[torque] Support bitfield structs stored within Smis" 
This reverts commit e5e4ea962e.

Reason for revert: mysterious performance regression chromium:1052756

Original change's description:
> [torque] Support bitfield structs stored within Smis
>
> This change moves the definition of the bits stored in DebugInfo::flags
> to Torque, and updates the only Torque usage of that field to use more
> natural syntax. This is intended as an example of common patterns found
> in various other classes. Several supporting changes are required:
>
> 1. Add a new type representing a bitfield struct stored within a Smi. It
>    is currently called SmiTagged, but I'm open to suggestions.
> 2. Add an enum-style output for Torque bitfield structs whose bitfields
>    occupy only one bit each.
> 3. Add a new case to MachineOperatorReducer that makes the generated
>    code for IncBlockCounter match with what was generated before this
>    change.
> 4. Add support for reporting these bitfields in the postmortem debugging
>    API. The format matches existing bitfields but with an offset value
>    that includes the SMI shift size.
>
> Bug: v8:7793
